Use the Multicast > Multicast Routing > Information page or the IPv6
Multicast > Multicast Routing > Information page to display IPv4 or IPv6
information on each multicast route the switch has learned through PIM.
The router learns multicast routes from neighboring routers, and also
advertises these routes to its neighbors. The router stores entries for all
paths learned by itself or from other routers, without considering actual
group membership or prune messages. The routing table therefore does
not indicate that the router has processed multicast traffic from any
particular source listed in the table. It uses these routes to forward
multicast traffic only if group members appear on directly-attached
subnetworks or on subnetworks attached to downstream routers.

These parameters are displayed for IPv4:
Show Summary
◆ Group Address – IP group address for a multicast service.
◆ Source Address – Subnetwork containing the IP multicast source.
◆ Source Mask – Network mask for the IP multicast source. Note that
the switch cannot detect the source mask, and therefore displays
255.255.255.255 in this field. (This parameter applies to IPv4 only.)
◆ Interface – Upstream interface leading to the upstream neighbor.
PIM creates a multicast routing tree based on the unicast routing table.
If the related unicast routing table does not exist, PIM will still create a
multicast routing entry, displaying the upstream interface to indicate
that this entry is valid. This field may also display “Register” to indicate
