that a pseudo interface is being used to receive PIM-SM register
packets. This can occur for the Rendezvous Point (RP), which is the root
of the Reverse Path Tree (RPT). In this case, any VLAN receiving
register packets will be converted into the register interface.
◆ Owner – The associated multicast protocol (PIM-DM, PIM-SM, IGMP
Proxy for PIMv4, MLD Proxy for PIMv6).
◆ Flags – The flags associated with each routing entry indicate:
■
Forward – Traffic received from the upstream interface is being
forwarded to this interface.
■
Local – This is the outgoing interface.
■
Pruned – This interface has been pruned by a downstream
neighbor which no longer wants to receive the traffic.

◆ 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.
◆ Upstream Neighbor – The multicast router (RPF Neighbor)
immediately upstream for this group.
◆ Upstream Interface – Interface leading to the upstream neighbor.
◆ Up Time – Time since this entry was created.
◆ Owner – The associated multicast protocol (PIM-DM, PIM-SM, IGMP
Proxy for PIMv4, MLD Proxy for PIMv6).
◆ Flags – The flags associated with each routing entry indicate:
■
Dense – PIM Dense mode in use.
■
Sparse – PIM Sparse mode in use.
■
Connected – This route is directly connected to the source.
■
Pruned – This route has been terminated.
■
Register flag – This device is registering for a multicast source.
■
RPT-bit set – The (S,G) entry is pointing to the Rendezvous Point
(RP), which normally indicates a pruned state along the shared tree
for a particular source.
■
SPT-bit set – Multicast packets have been received from a source
on shortest path tree.
