The output shows that GigabitEthernet 2/1/3 and GigabitEthernet 2/1/4 of Device A has joined
multicast group 224.1.1.1.

Static port configuration example

Network requirements
As shown in
Device C, with Router A acting as the IGMP querier.
Host A and host C are permanent receivers of multicast group 224.1.1.1. GigabitEthernet 2/1/3 and
GigabitEthernet 2/1/5 on Device C are required to be configured as static member ports for multicast
group 224.1.1.1 to enhance the reliability of multicast traffic transmission.
Suppose STP runs on the network. To avoid data loops, the forwarding path from Device A to Device C
is blocked under normal conditions, and multicast traffic flows to the receivers attached to Device C only
along the path of Device A—Device B—Device C. Configure GigabitEthernet 2/1/3 that connects
Device A to Device C as a static router port, so that multicast traffic can flows to the receivers nearly
uninterruptedly along the path of Device A—Device C in the case that the path of Device A—Device
B—Device C gets blocked.
NOTE:
If no static router port is configured, when the path of Device A—Device B—Device C gets blocked, at least
one IGMP query-response cycle must be completed before the multicast data can flow to the receivers
along the new path of Device A—Device C, namely multicast delivery will be interrupted during this
process.

Guide.
