Parameters
vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a VPN instance, this command displays multicast routing entries on the public network.
source-address: Specifies a multicast source address.
group-address: Specifies a multicast group address in the range of 224.0.0.0 to 239.255.255.255.
mask-length: Specifies an address mask length. The default value is 32. For a multicast group address, the value range for this argument is 4 to 32. For a multicast source address, the value range for this argument is 0 to 32.
mask: Specifies an address mask. The default is 255.255.255.255.
incoming-interface: Specifies the multicast routing entries that contain the specified incoming interface.
interface-type interface-number: Specifies an interface by its type and number.
outgoing-interface: Specifies the multicast routing entries that contain the specified outgoing interface.
exclude: Specifies the multicast routing entries that do not contain the specified interface in the outgoing interface list.
include: Specifies the multicast routing entries that contain the specified interface in the outgoing interface list.
match: Specifies the multicast routing entries that contain only the specified interface in the outgoing interface list.
Usage guidelines
Multicast routing entries are the basis of multicast forwarding. You can use this command to view the establishment state of (S, G) entries.
