Customizing Multicast Routing
Configuring IGMP Group Membership
You can configure the ASA to be a member of a multicast group. Configuring the ASA to join a multicast
group causes upstream routers to maintain multicast routing table information for that group and keep
the paths for that group active.
Note
If you want to forward multicast packets for a specific group to an interface without the ASA accepting
those packets as part of the group, see the
“Configuring a Statically Joined IGMP Group” section on
.
To have the ASA join a multicast group, enter the following command:
Configuring a Statically Joined IGMP Group
Sometimes a group member cannot report its membership in the group because of some configuration,
or there may be no members of a group on the network segment. However, you still want multicast traffic
for that group to be sent to that network segment. You can have multicast traffic for that group sent to
the segment by configuring a statically joined IGMP group.
Enter the
igmp static-group
command. The ASA does not accept the multicast packets, but instead
forwards them to the specified interface.
To configure a statically joined multicast group on an interface,enter the following command:
