The following table describes the virtual router’s Runtime Stats for IP Multicast.
Multicast Runtime Stats
Multicast group address that the VR will forward.
Multicast source address.
Indicates interfaces where the multicast traffic comes in on the VR.
IGMP Interface Tab
Interface that has IGMP enabled.
Version 1, 2, or 3 of Internet Group Management Protocol (IGMP).
IP address of the IGMP querier on that interface.
Querier Up Time
Length of time that IGMP querier has been up.
Querier Expiry Time
Time remaining before the current the Other Querier Present timer expires.
Robustness variable of the IGMP interface.
Number of multicast groups allowed on the interface.
Number of multicast sources allowed on the interface.
Yes or no indicates whether Immediate Leave is configured. Immediate leave indicates that the virtual router will remove an interface from the forwarding table entry without sending the interface IGMP group-specific queries.
IGMP Membership Tab
Name of an interface to which the membership belongs.
IP Multicast group address.
Source address of multicast traffic.
Length of time this membership been up.
Length of time remaining before membership expires.
Include or exclude the source. VR is configured to include all traffic, or only traffic from this source (include), or traffic from any source except this one (exclude).
Time remaining before the interface Exclude state expires.
V1 Host Timer
Time remaining until the local router assumes that there are no longer any IGMP Version 1 members on the IP subnet attached to the interface.
V2 Host Timer
Time remaining until the local router assumes that there are no longer any IGMP Version 2 members on the IP subnet attached to the interface.
PIM Group Mapping Tab
IP address of the group mapped to a Rendezvous Point.
IP address of Rendezvous Point for the group.
Indicates where the VR learned of the RP.
ASM or SSM.
Indicates that the mapping of the group to the RP is inactive.
PIM Interface Tab
Name of interface participating in PIM.
IP address of the interface.
IP address of the Designated Router on the interface.
Hello interval configured, in seconds.
Join/Prune interval configured, in seconds.
Assert interval configured, in seconds.
Priority configured for the Designated Router.
Yes or no.
PIM Neighbor Tab
Name of interface in the VR.
IP address of the neighbor.
Secondary IP address of the neighbor.
Length of time the neighbor has been up.
Length of time remaining before the neighbor expires because the VR is not receiving hello packets from the neighbor.
Value that the VR received from the neighbor in the last PIM hello message received on this interface.
Designated Router priority that the VR received in the last PIM hello message from this neighbor.

PIM Assert Mechanism
PIM uses an Assert mechanism to elect a PIM Forwarder of multicast packets on a multiaccess network, which prevents forwarding of duplicate multicast packets. ...
A virtual router supports IP multicast so that it can participate in multicast protocols (IGMP and PIM) and forward multicast traffic from a source to ...
PIM Sparse Mode supports Any-Source Multicast (ASM) and Source-Specific Multicast (SSM); ASM requires a rendezvous point (RP). Configure PIM on ingress and egress interfaces for ...
PIM uses reverse-path forwarding (RPF) to prevent routing loops and to build a shortest-path tree from the receiver back to the multicast source. ...
Shortest-Path Tree (SPT) and Shared Tree
IP Multicast constructs shortest-path tree (SPT) and shared tree distribution paths to forward multicast packets to members of a group. ...
