Chapter 31: Ipv6 Multicast Commands - Extreme Networks ExtremeWare XOS Command Reference Manual

ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.
31 IPv6 Multicast Commands
IPv6 multicast is a function that allows a single IPv6 host to send a packet to a group of IPv6 hosts. This
group of hosts can include devices that reside on or outside the local network, or within or across a
routing domain.
IPv6 multicast routing consists of the following functions:
A router that can forward IPv6 multicast packets
●
A router-to-router multicast protocol [for example, Protocol Independent Multicast (PIM)]
●
A method for the IPv6 host to communicate its multicast group membership to a router [for
●
example, Multicast Listener Discovery (MLD)]
NOTE
You must configure IPv6 unicast routing before you configure IPv6 multicast routing.
MLD is a protocol used by an IPv6 host to register its IP multicast group membership with a router.
Periodically, the router queries the multicast group to see if the group is still in use. If the group is still
active, a single IP host responds to the query, and group registration is maintained.
MLDv1 is currently supported on the switch.
NOTE
In the current release of ExtremeWare XOS (11.4), IPv6 multicast packets are flooded to VLANs that receive the
traffic, therefore, MLD snooping is not supported. Also, ExtremeWare XOS does not currently support any IPv6
multicast routing protocols.
