When MLD snooping or PIM snooping for IPv6 is enabled, the forwarding of IPv6 multicast traffic is MAC-based; see MAC-based IPv6 multicast forwarding for more information.
The operation with PIM snooping for IPv6 can be changed to SG-based forwarding; see SG-based IPv6 multicast forwarding for more information.
The following command configures the IPv6 multicast forwarding mode with the default being mac-based:
configure service vpls mcast-ipv6-snooping-scope {sg-based | mac-based}
The forwarding mode can only be changed when PIM snooping for IPv6 is disabled.
