Dest. MAC
- the destination MAC address of the multicast
Source MAC
- the MAC address of the MP from which the
multicast originated (The actual source may be an NMP
behind the MP.)
Prev. Hop MAC
- the MAC address of the previous hop in
the multicast route
Interface
- the interface on which the multicast is received, if
it is an Access interface (Core interfaces show N/A, not
applicable.)
Talker
- whether the current MP is a sender for the
destination MAC address (
yes
) or only a listener (
no
)
An MP becomes a talker for a multicast group when it
receives a packet from a sender on one of the MP’s FP
Mesh Access interfaces, or when the MP is manually
configured as a
Talker
(refer to Section 3.2.1.7). MPs do not
show up as talkers on broadcast flows, even though the
broadcast source may be on one of the MP’s Access
interfaces.
Forwarding On
- the interfaces on which the multicast on
this route is forwarded.

FastPath Mesh Multicast Groups
A FastPath MP automatically subscribes to and leaves
multicast groups on behalf of NMPs by snooping IP multicast
control messages on FP Mesh Access interfaces. You can also
establish multicast stream subscriptions manually (refer to
Section 3.2.1.7). Regardless of how they were established,
