Introduction

This document describes how to configure each Multicast VPN (mVPN) profile within the Cisco IOS®XR.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

Note: The configurations that are described in this document apply to the Provider Edge (PE) routers.

Prerequisites

Requirements

Cisco recommends that you verify whether there is support for an mVPN profile on the specific platform that runs Cisco IOS-XR.

Components Used

The information in this document is based on all versions of Cisco IOS-XR.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Configure

mVPN Profile

An mVPN profile is configured for the global context or per Virtual Routing/Forwarding (VRF). This is specified under the Multicast-Routing section within the Cisco IOS-XR.

Global Context

Here is the mVPN configuration for the global context:

multicast-routing

address-family ipv4

mdt mldp in-band-signaling ipv4

VRF Context

Here is the mVPN configuration for the VRF context:

multicast-routing

vrf one

address-family ipv4

mdt mldp in-band-signaling ipv4

mdt partitioned mldp ipv4 p2mp (bidir)

mdt partitioned mldp ipv4 mp2mp (bidir)

mdt partitioned ingress-replication

mdt mldp in-band-signaling ipv4

mdt default mldp ipv4 <root>

mdt default mldp p2mp (partitioned)(bidir)

mdt default ingress-replication

mdt default <ipv4-group>

mdt default (ipv4) <ipv4-group> partitioned

mdt data <ipv4-group/length>

mdt data <max nr of data groups> (threshold)

mdt static p2mp-te tunnel-te <0-65535>

mdt static tunnel-mte <0-65535>

Note: VRF one is used throughout the document. The Rosen MLDP has been renamed to Default MDT.

Some deployment models or profiles cannot coexist. When you attempt to configure them, an error message pops up when you commit the configuration. Here is an example:

RP/0/3/CPU0:Router(config-mcast-one-ipv4)#show conf fail

!! SEMANTIC ERRORS: This configuration was rejected by

!! the system due to semantic errors. The individual

!! errors with each failed configuration command can be

!! found below.

multicast-routing

vrf one

address-family ipv4

mdt default mldp p2mp

!!% Invalid MLDP MDT type: MDT Default MLDP P2MP cannot co-exist with MDT Default

MLDP (Rosen MLDP)or Partitioned MDT MLDP

!

!

!

end

The mdt default mldp ipv4 10.1.100.1 is already configured, which specifies the profile MDT Default MLDP.

Always specify the Multicast Distribution Tree (MDT) source interface, for the global context or the VRF:

multicast-routing

address-family ipv4

interface Loopback0

enable

!

mdt source Loopback0

mdt mldp in-band-signaling ipv4

rate-per-route

interface all enable

accounting per-prefix

!

vrf one

address-family ipv4

mdt source Loopback0

mdt default mldp ipv4 10.1.100.7

rate-per-route

interface all enable

accounting per-prefix

!

!

!

Always enable the loopback interface under the multicast-routing section in the global context:

multicast-routing

address-family ipv4

interface Loopback0

enable

VPN-ID

The VPN-ID that is configured under the VRF is only needed for the profiles that use the Multipoint Label Distribution Protocol (MLDP) as the core tree protocol, MP2MP, and Default MDT.

vrf one

vpn id 1000:2000

address-family ipv4 unicast

import route-target

1:1

!

export route-target

1:1

!

!

Core Tree

It is possible for multiple MDTs or core trees to be configured and signaled. In order to specify the core tree that the multicast traffic should take, a Reverse Path Forwarding (RPF) policy should be configured. This is done with a route-policy. The egress Provider Edge (PE) then initiates the core tree based on the RPF policy. Use the rpf topology route-policy route-policy-name command in order to complete this action. This is the route-policy that is applied under the section for the router Protocol Independent Multicast (PIM).

In the route-policy, you can optionally set the core tree after you specify an IF-statement:

RP/0/3/CPU0:Router(config-rpl)#set core-tree ?

ingress-replication-default      Ingress Replication Default MDT core

ingress-replication-partitioned  Ingress Replication Partitioned MDT core

mldp-default                     MLDP Default MDT core

mldp-inband                      MLDP Inband core

mldp-partitioned-mp2mp           MLDP Partitioned MP2MP MDT core

mldp-partitioned-p2mp            MLDP Partitioned P2MP MDT core

p2mp-te-default                  P2MP TE Default MDT core

p2mp-te-partitioned              P2MP TE Partitioned MDT core

parameter                        Identifier specified in the format: '$'

followed by alphanumeric characters

pim-default                      PIM Default MDT core

The configuration for the Multiprotocol Label Switching (MPLS) Traffic Engineering (TE) must be in place for the Point-to-Multipoint (P2MP) TE profiles. This means that the link-state routing protocol Open Shortest Path First (OSPF) or Intermediate System-to-Intermediate System (IS-IS) must be enabled for MPLS TE, and the MPLS TE must be enabled with the core interfaces specified and an MPLS TE router-ID. Some P2MP TE profiles have auto-tunnels. This must be explicitly enabled. The Resource Reservation Protocol (RSVP)-TE must be enabled as well.

Data MDTs

Data MDTs are an optional configuration. The number of data MDTS can be specified for any type of core tree protocol or for a specific type of core tree protocol.

Here is an example that specifies the data MDTs for any type of core tree protocol:

multicast-routing

vrf one

address-family ipv4

mdt source Loopback0

mdt data 100

rate-per-route

interface all enable

accounting per-prefix

!

!

!

Here is an example that specifies the data MDTs for one specific type of core tree protocol:

multicast-routing

vrf one

address-family ipv4

mdt source Loopback0

mdt data 232.1.100.0/24

mdt data mldp 100

rate-per-route

interface all enable

accounting per-prefix

!

!

!

mdt data ingress-replication 100

Customer Multicast Signaling

Customer Multicast Signaling or C-Mcast Signaling (also referred to as overlay signaling) is performed by either PIM or Border Gateway Protocol (BGP). The default is PIM. In order to configure BGP to perform the C-Multicast Signaling, you must configure this PIM command in the VRF context:

router pim

...

vrf one

address-family ipv4

...

mdt c-multicast-routing bgp

BGP Address Family IPv4 MVPN

The Address Family (AF) IPv4 mVPN must be enabled when BGP-Auto Discovery (BGP-AD) and/or BGP C-Multicast Signalling is needed. The AF IPv4 mVPN must then be enabled in three places:

- Globally

- For the internal Border Gateway Protocol (iBGP) peers (these are the other PE routers or the Route Reflectors (RRs))

- For the VRF

Here is an example:

router bgp 1

address-family ipv4 unicast

redistribute connected

!

address-family vpnv4 unicast

!

address-family ipv6 unicast

!

address-family ipv4 mdt

remote-as 65001

address-family ipv4 unicast

route-policy pass in

route-policy pass out

!

!

!

!

mVPN Keyword Under Router BGP

In some specific cases, the mvpn keyword is required in the router BGP section:

router bgp 1

mvpn

address-family ipv4 unicast

redistribute connected

!

address-family vpnv4 unicast

..

These are the cases when mVPN must be configured:

- It is required for profile 6, if BGP does not have MDT or mVPN Subsequent Address Family Identifiers (SAFIs) configured.

- It is required for profile 2, if BGP does not have MDT or mVPN SAFIs configured.

Profiles

This section describes the required configurations on the PE routers for each profile. Ensure that you read the previous sections of this document before you attempt these configurations, which describe some required configurations that are not repeated for each profile. Here are some examples:

- Specification of the MDT source interface

- Enablement of the loopback interface under the multicast-routing section

- Configuration of the required BGP AF and commands

Inter-Autonomous mVPN

This section describes how to configure an inter-Autonomous System (inter-AS) mVPN.

Note: The information that is described in the next sections is provided under the assumption that the proper configuration is completed on the routers for inter-autonomous MPLS VPN unicast.

Option A

The regular mVPN configuration is needed. You can have any profile in the autonomous systems, and they do not have to match in the different autonomous systems.

The Options B and C are discussed further per core tree protocol. When you configure external Border Gateway Protocol (eBGP) on the Autonomous System Border Routers (ASBRs), do not forget to configure a route-policy in and out for either AF IPv4 MDT or AF IPv4 MVPN.

Check whether this configuration is required on an ASBR for Inter-AS Option B or C with PIM or MLDP as core tree protocol:

router bgp 1

!

address-family ipv4|ipv6 mvpn

inter-as install

!

PIM

For inter-AS mVPN, an IOS-XR router running older IOS-XR does not have a method to originate the PIM vector. In that case, the IOS-XR router cannot be a PE router. This means that Inter-AS Options B and C, Seamless MPLS, and BGP-free Core are not possible. An IOS-XR router does understand the PIM vector, so the router can be a P (Provider) router or an ASBR. In later IOS-XR releases, the IOS-XR PE router can originate the PIM vector, without Route Distinguisher (RD). In that case, it can be the PE router for BGP-free core, Inter-AS Option C and Seamless MPLS.

The PIM (RPF) vector is a PIM proxy that allows core routers without RPF information forward PIM Join and Prune messages for external sources.

To originate the PIM RPF-Vector in IOS-XR:

router pim

address-family ipv4

rpf-vector

!

!

!

Note: The rpf-vector inject command is not related to the inter-AS mVPN, but it is a command that is required for the TI-Multicast only Fast Re-Route (TI-MoFRR).

Here is the configuration that is required on an IOS-XR P router in order to interpret the PIM vector:

router pim

address-family ipv4

rpf-vector

When AF IPv4 mVPN is used instead of AF IPv4 MDT, the BGP-AD with PIM is needed for inter-AS. Thus, this configuration is required:

multicast-routing

vrf one

address-family ipv4

bgp auto-discovery pim

inter-as

The AF IPv4 MDT has inherent inter-AS support, as the connector attribute is a transient attribute. No keyword is required in order to make AF IPv4 MDT inter-AS-capable.

The AF IPv4 and AF IPv4 mVPN can be configured at the same time.

When the bgp auto-discovery pim command is configured, the PE router sends out the BGP-AD type 1 route, with the no-export community. When the bgp auto-discovery pim and inter-as commands are configured, the PE router sends out the BGP AD type 1 route, without the no-export community.

Whether the bgp auto-discovery pim command  is configured or not, type 6 and 7 routes can be originated in the AF IPv4 mVPN if this configuration is applied:

router pim

vrf one

address-family ipv4

rpf topology route-policy rpf-for-one

mdt c-multicast-routing bgp

!

interface GigabitEthernet0/0/0/9

enable

!

!

!

!

It is possible to have the BGP-AD completed by the AF IPv4 MDT and the C-multicast signaling by the BGP AF IPv4 mVPN. In order for this to occur, you must have the mdt c-multicast-routing bgp command configured under router PIM, but not the bgp auto-discovery pim command under Multicast-Routing section.

Note: You can have both types of BGP-ADs configured: AF IPv4 MDT and AF IPv4 mVPN.

Option B

Inter-AS mVPN Option B without redistribution of the PE loopbacks into the Interior Gateway Protocol (IGP) of the other AS is not possible if the PE router runs Cisco IOS-XR, because the PE router cannot originate the PIM vector with the Route Distinguisher (RD).

The scenario where the PE loopbacks are redistributed into the IGP of the other AS is supported.

If AF IPv4 mVPN is used, then this additional configuration on the PE router is required:

multicast-routing

vrf one

address-family ipv4

mdt source Loopback0

mdt ...

rate-per-route

interface all enable

bgp auto-discovery pim

inter-as

Note: When AF IPv4 MDT is used, the bgp auto-discovery pim command is not required.

Option C

Inter-AS mVPN Option C without redistribution of the PE loopbacks into the IGP of the other AS is possible if the PE router runs IOS-XR, because the PE router can originate the PIM vector without the Route Distinguisher (RD).

The scenario where the PE loopbacks are redistributed into the IGP of the other AS is also supported.

If AF IPv4 mVPN is used, then this additional configuration on the PE router is required:

multicast-routing

vrf one

address-family ipv4

mdt source Loopback0

mdt ...

rate-per-route

interface all enable

bgp auto-discovery pim

inter-as

Note: When AF IPv4 MDT is used, the bgp auto-discovery pim command is not required.

MLDP

This section describes how to configure the MLDP.

Redistribution of PE Loopbacks into IGP of other AS

If the PE loopbacks are redistributed into the IGP of the other AS, it is similar to intra-AS mVPN with MLDP. Recursive Forwarding Equivalence Class (FEC) is not needed. Still, the BGP-AD updates must make it to the other AS. For this reason, this configuration is required on the PE router:

multicast-routing

vrf one

address-family ipv4

mdt source Loopback0

mdt mldp in-band-signaling ipv4

rate-per-route

interface all enable

bgp auto-discovery mldp

inter-as

!

accounting per-prefix

!

!

!

AF IPv4 mVPN must be configured on the PE routers and RRs or ASBRs:

router bgp 1

address-family ipv4 unicast

redistribute connected

!

address-family vpnv4 unicast

!

!

address-family ipv4 rt-filter

!

address-family ipv4 mvpn

!

neighbor 10.1.100.7   <<< iBGP neighbor

remote-as 1

update-source Loopback0

address-family vpnv4 unicast

!

!

address-family ipv4 mvpn

!

!

!

vrf one

!

address-family ipv4 mvpn

!

!

No Redistribution of PE Loopbacks into IGP of other AS

In this case, MLDP Recursive FEC is required.

Option B

This additional configuration on the PE router is required:

multicast-routing

vrf one

address-family ipv4

mdt source Loopback0

mdt mldp in-band-signaling ipv4

rate-per-route

interface all enable

bgp auto-discovery mldp

inter-as

!

accounting per-prefix

!

!

!

mpls ldp

mldp

logging notifications

address-family ipv4

recursive-fec

!

Note: Recursive FEC is not required on the ASBRs.

router bgp 1

address-family ipv4 unicast

redistribute connected

!

address-family vpnv4 unicast

!

!

address-family ipv4 rt-filter

!

address-family ipv4 mvpn

!

neighbor 10.1.100.7   <<< iBGP neighbor

address-family vpnv4 unicast

!

!

address-family ipv4 mvpn

!

!

!

vrf one

!

address-family ipv4 mvpn

!

!

The MLDP must be enabled on the link between the ASBRs. This additional configuration on the ASBR is required:

mpls ldp

router-id 10.1.100.7

mldp

logging notifications

!

interface GigabitEthernet0/7/0/0   <<< ASBR-ASBR link

!

Because there is now an eBGP session with AF ipv4 mvpn enabled, a route-policy in and out is required for the eBGP session:

router bgp 1

!

address-family vpnv4 unicast

retain route-target all

!

address-family ipv4 mvpn

!

address-family ipv6 mvpn

!

neighbor 10.1.5.3     <<< eBGP neighbor (ASBR)

remote-as 2

address-family vpnv4 unicast

route-policy pass in

route-policy pass out

!

address-family ipv4 mvpn

route-policy pass in

route-policy pass out

!

Option C

This additional configuration on the PE router is required:

multicast-routing

vrf one

address-family ipv4

mdt source Loopback0

mdt ...

rate-per-route

interface all enable

bgp auto-discovery mldp

inter-as

!

accounting per-prefix

!

!

!

mpls ldp

mldp

address-family ipv4

recursive-fec

!

Note: Recursive FEC is not required on the ASBRs.

router bgp 1

!

address-family ipv4 rt-filter

!

address-family ipv4 mvpn

!

neighbor 10.1.100.7   <<< iBGP neighbor

remote-as 1

update-source Loopback0

address-family vpnv4 unicast

!

!

address-family ipv4 mvpn

!

!

!

vrf one

!

address-family ipv4 mvpn

!

!

The MLDP must be enabled on the link between the ASBRs. This additional configuration on the ASBR is required:

mpls ldp

router-id 10.1.100.7

mldp

logging notifications

!

interface GigabitEthernet0/7/0/0   <<< ASBR-ASBR link

!

Because there is now an eBGP session with AF ipv4 mvpn enabled on the RR, a route-policy in and out is required for the eBGP session.
