6.21.2 Displaying the Multicast Routing Table
The router can display information on each multicast route it has learned through
DVMRP or 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.
Field Attributes
• Group Address – IP group address for a multicast service.
• Source Address – Subnetwork containing the IP multicast source.
• Netmask – Network mask for the IP multicast source.
• Interface – Interface leading to the upstream neighbor.
• Owner – The associated multicast protocol (DVMRP or PIM).
