The output shows that GigabitEthernet 1/0/3 and GigabitEthernet 1/0/4 of Switch A have joined IPv6
multicast group FF1E::101.
Static port configuration example
Network requirements
•
As shown in Figure 67 , Router A connects to an IPv6 multicast source—Source—through
GigabitEthernet 1/0/2 and to Switch A through GigabitEthernet 1/0/1.
•
MLDv1 runs on Router A, and MLDv1 snooping runs on Switch A, Switch B and Switch C, with
Router A acting as the MLD querier.
•
Host A and Host C are permanent receivers of IPv6 multicast group FF1E::101. GigabitEthernet
1/0/3 and GigabitEthernet 1/0/5 on Switch C are required to be configured as static member
ports for multicast group FF1E::101 to enhance the reliability of multicast traffic transmission.
•
Suppose STP runs on the network. To avoid data loops, the forwarding path from Switch A to
Switch C is blocked under normal conditions, and IPv6 multicast traffic flows to the receivers
attached to Switch C only along the path of Switch A—Switch B—Switch C.
•
You must configure GigabitEthernet 1/0/3 that connects Switch A to Switch C as a static router
port, so that IPv6 multicast traffic can flow to the receivers nearly uninterruptedly along the path of
Switch A—Switch C in the case that the path of Switch A—Switch B—Switch C becomes blocked.
NOTE:
If no static router port is configured, when the path of Switch A—Switch B—Switch C becomes
blocked, at least one MLD query-response cycle must be completed before the IPv6 multicast data can
flow to the receivers along the new path of Switch A—Switch C. Namely, IPv6 multicast delivery will
be interrupted during this process.
