Cisco IOS XE 3S Release Notes for the Cisco ASR 903 Router
26
You configure Protocol-Independent Multicast-Sparse Mode (PIM-SM) with a static
rendezvous point (RP).
You create an EVC port channel on the access side with one member link
You create bridge domain interfaces (BDIs) with 1:1 mapping between EVCs and
bridge-domains.
You use the BDIs to send IGMP v2 static join messages to a single multicast group
On the remote device, you create 150 EFPs and map them to the BDIs.
You initiate multicast traffic.
You set the EFPs to the default configuration and add them to the existing port-channel
You configure Protocol-Independent Multicast-Sparse Mode (PIM-SM) with a static
rendezvous point (RP).
You configure a bridge domain interface (BDI) on the PE2 access side
You use the BDI to send IGMP v2 static join messages to a single multicast group
You disable IGMP snooping globally.
You configure 24 EFPs and map them to a single bridge-domain.
You initiate multicast traffic.
