3Com Switch 8800 Advanced Software V5 Configuration Guide

MLD Snooping Configuration Examples 665
■ MLD runs between Router A and Switch A, MLD Snooping runs on Switch A,
and Router A acts as the MLD querier.
■ Router A runs IPv6 PIM-SM, and the Ethernet1/1/2 serves as C-BSR and C-RP.
■ Perform the following configuration so that multicast data (1::1,
FE1E::101:101) can be forwarded through Ethernet1/2 and Ethernet1/3 even if
the receivers Host A and Host B attached to on Switch A temporarily stop
receiving IPv6 multicast data for some unexpected reasons.

Configuration procedure
1 Configure the IPv6 address of each interface
Configure an IPv6 address and address prefix for each interface. The detailed
configuration steps are omitted.
2 Configure Router A
# Enable IPv6 multicast routing, enable IPv6 PIM-SM on each interface, and enable
MLDv1 on Ethernet1/1/1. The Ethernet1/1/2 serves as C-BSR and C-RP.
