R2511-HP MSR Router Series IP Multicast Command Reference(V5)
258
Usage guidelines
To specify a multicast group address on the public network SSM group range as a share-group address,
you must first configure BGP MDT peers or peer groups.
On the same PE device, different VPN instances must not have the same group address, and
group-address must not coincide with the switch-group address of any VPN instance; in addition,
mtunnel-number must not coincide with the number of any MTI already created.
This command must not be used multiple times in the same VPN instance view. To configure a new group
address and MTI for a VPN instance, you must remove the existing configuration.
The undo multicast-domain share-group command removes the configured MTI and the configurations
of the multicast-domain switch-group-pool, multicast-domain log switch-group-reuse and
multicast-domain switch-delay commands.
Enable IP multicast routing for the VPN instance before you configure this command.
