Forcing Ingress Multicast Replication Mode (Optional)
The MVPN feature supports only ingress multicast replication mode. If the switch is currently configured for egress replication, it is forced into ingress replication when the first MVRF is configured. This change in replication mode automatically purges all forwarding entries in the hardware, temporarily forcing the switch into software switching until the table entries can be rebuilt.
To avoid disrupting customer traffic, we recommend verifying that the switch is already in ingress multicast replication mode before configuring any MVRFs. This example shows how to verify the multicast replication mode: Router# show platform ip multicast capability Current mode of replication is Ingress auto replication mode detection is ON Slot Multicast replication capability 2 Egress 5 Egress 6 Egress 8 Ingress 9 Ingress 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:
