As shown above, GigabitEthernet 2/0/3 and GigabitEthernet 2/0/4 of Switch A have joined IPv6
multicast group FF1E::101.
Static Port Configuration Example
Network requirements
z
As shown in
, Router A connects to an IPv6 multicast source (Source) through
GigabitEthernet 2/0/2, and to Switch A through GigabitEthernet 2/0/1.
z
MLDv1 is to run on Router A, and MLDv1 Snooping is to run on Switch A, Switch B and
Switch C, with Router A acting as the MLD querier.
z
Host A and host C are permanent receivers of IPv6 multicast group FF1E::101.
GigabitEthernet 2/0/3 and GigabitEthernet 2/0/5 on Switch 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.
z
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.
z
It is required to configure GigabitEthernet 2/0/3 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 gets blocked.
If no static router port is configured, when the path of Switch A—Switch B—Switch C gets
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.
