MLD snooping configuration examples
IPv6 group policy and simulated joining configuration
example (for VLANs)
Network requirements
As shown in
, Router A runs MLDv1 and acts as the MLD querier, and Switch A runs MLDv1
snooping.
Configure a group policy to achieve the following goals:
•
Host A and Host B receive only the IPv6 multicast data addressed to IPv6 multicast group
FF1E::101. In addition, IPv6 multicast data is uninterruptedly forwarded through
GigabitEthernet 1/0/3 and GigabitEthernet 1/0/4 of Switch A, even though Host A and Host B
temporarily fail.
•
Switch A drops unknown IPv6 multicast data instead of flooding it in VLAN 100.
