Configuring A Multicast Vpn Routing And Forwarding Instance - Cisco 7604 Configuration Manual

Chapter 25 Configuring IPv4 Multicast VPN Support
To avoid disrupting customer traffic, we recommend verifying that the router is already in ingress
multicast replication mode before configuring any MVRFs.
This example shows how to verify the multicast replication mode:
Router# show mls ip multicast capability
Current mode of replication is Ingress
auto replication mode detection is ON
Slot
Router#
If the current replication mode is egress or if any of the switching modules are capable of egress
replication mode, configure ingress replication mode during a scheduled maintenance period to
minimize the disruption of customer traffic.
To configure ingress multicast replication mode, perform this task:
Command
Step 1
Router# configure terminal
Step 2
Router(config)# mls ip multicast replication-mode
ingress
Router(config)# no mls ip multicast
replication-mode ingress
Step 3
Router(config)# do show mls ip multicast
capability | include Current
This example shows how to configure ingress multicast replication mode and verify the configuration:
Router(config)# mls ip multicast replication-mode ingress
Router(config)# do show mls ip multicast capability | include Current
Current mode of replication is Ingress

Configuring a Multicast VPN Routing and Forwarding Instance

These sections describe how to configure a multicast VPN routing and forwarding (MVRF) instance for
each VPN connection on each PE router that is to handle the traffic for each particular VPN connection
that is to transmit or receive multicast traffic:
