Description |
|---|---|
|
Cisco Catalyst 8500-20X6C Edge Platform |
The Cisco Catalyst 8500-20X6C Edge Platform, as part of the Catalyst 8500 series of routers, is available from Cisco IOS XE Dublin 17.10.x. The C8500-20X6C router is designed to provide high-speed connectivity and advanced security features for enterprise networks. For more information on this, refer to the Cisco Catalyst 8500 Series Edge Platforms Hardware Installation Guide and Software Configuration Guide. |
New and Changed Software Features
|
Feature |
Description |
|---|---|
|
This feature provides support for IPv6 multicast in PPPoE-based Radio Aware Routing (RAR) networks. |
|
|
This feature introduces new methods of attaching extended color communities to a prefix. A color community is an indicator of the bandwidth or latency level of the traffic sent to the prefix. You can attach the the extended color communities to the prefix in the following ways: VRF export coloring, VRF import coloring, Route Redistribution coloring into BGP and Neighbor inbound coloring. |
|
|
Upgrade in IPsec Tunnel Scaling Limits for High-End Aggregation |
IPsec FlexVPN tunnel scale is improved for QFP 3.0 based Catalyst 8500 platforms |
|
Support for Radio Aware Routing (RAR) and Dynamic Link Exchange Protocol (DLEP) |
This feature enables Radio-Aware Routing (RAR) support on Cisco Catalyst 8000 Edge Platforms. RAR is a mechanism that uses radio signals to interact with the routing protocol OSPFv3 to signal the appearance, disappearance, and link conditions of one-hop routing neighbors. Cisco Dynamic Link Exchange Protocol (DLEP) is the latest protocol in the RAR family. DLEP provides a bidirectional, event-driven communication channel between the router and the modem/radio to facilitate communication of changing link characteristics. |
|
Device Telemetry |
This functionality enables collection of anonymous usage telemetry data for Cisco products, which helps in continuous product improvements. From Cisco IOS XE 17.11.1a, this functionality is enabled by default. |
|
Replication of Broadcast, Unknown-unicast, and Multicast Traffic |
With this enhancement, the multi-destination Layer 2 broadcast, unknown-unicast, and multicast (BUM) traffic in an EVPN VXLAN network is replicated through a multicast group in the underlay network and forwarded to all the endpoints of the network. |
|
MAC and IP Addressing Learning from a Static ARP Alias Entry |
This enhancement allows you to configure an EVPN VXLAN network to learn an EVPN MAC address and IP binding from a static Address Resolution Protocol (ARP) alias entry. After learning the MAC address and IP binding, an EVPN Type-2 route is advertised across the EVPN network. |
| Deprecation of weak ciphers |
The minimum Rivest, Shamir, and Adleman (RSA) key pair size must be 2048 bits. The compliance shield on the device must be disabled using the crypto engine compliance shield disable command to use the weak RSA key. |
