Router Port
Specify which ports act as router ports. A router port is a port on the Ethernet switch
that leads towards the Layer 3 multicast device or MLD querier. Normally, the router
port is the uplink port to the upper L3 Router or IGMP Querier. For example in below
figure, the green port of the 2 switches are Router port.
If an aggregation member port is selected as a router port, the whole aggregation
will act as a router port.
Fast Leave
Enable the fast leave on the port.
Multicast snooping Fast Leave processing allows the switch to remove an interface
from the forwarding-table entry without first sending out group specific queries to the
interface. The VLAN interface is pruned from the multicast tree for the multicast
group specified in the original leave message. Fast-leave processing ensures
optimal bandwidth management for all hosts on a switched network, even when
multiple multicast groups are in use simultaneously. This processing applies to
IGMP and MLD
