Introduction

This document describes how to configure router on a stick with a CGR2010 and Cisco Ethernet Switch Module (ESM).

Prerequisites

Requirements

Cisco recommends that you have knowledge of these topics:

Routing and Switching fundamentals
CGR2010 and ESM architecture.
CGR2010 must run Cisco IOS Release 15.1(4)M or higher in order to run the switch module.

Components Used

The information in this document is based on this hardware/software versions CGR2010 with Cisco IOS Release 15.1(4)M

The outputs in this document were taken from devices in a specific lab environment. All 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.

Configure

ESM Module:

!- - Default configuration - -! 

interface Port-channel48
 description Internal backplane interface. Use caution while changing the configuration
 switchport mode trunk
 end


 interface Vlan33
 ip address 192.168.33.33 255.255.255.0




interface Vlan44

ip address 192.168.44.44 255.255.255.0



interface Vlan55

ip address 192.168.55.55 255.255.255.0

Exit the ESM module. Press the key combination: ctrl + shift + 6 and then x .

Write discconect to finish the ESM session.

CGR2010 configuration :

interface GigabitEthernet0/0/0.33
 encapsulation dot1Q 33
 ip address 192.168.33.1 255.255.255.0
 end


interface GigabitEthernet0/0/0.44
 encapsulation dot1Q 44
 ip address 192.168.44.1 255.255.255.0
 end


interface GigabitEthernet0/0/0.55
 encapsulation dot1Q 55
 ip address 192.168.55.1 255.255.255.0
 end

Verify

Perform some pings from ESM to CGR2010 virtual interfaces:

Ping to 192.168.55.1 from all the SVI sources.

Switch#ping 192.168.55.1 source vlan 33

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.55.1, timeout is 2 seconds:

Packet sent with a source address of 192.168.33.33

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/9 ms

Switch#ping 192.168.55.1 source vlan 44

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.55.1, timeout is 2 seconds:
