The following table describes the virtual router’s Runtime Stats for IP multicast.
Multicast Runtime Stats
Route entry in the forwarding information base (FIB); multicast group address to which the virtual router will forward packets.
Source address of multicast packets for the group.
Interfaces where multicast packets for the group arrive.
Interfaces out which the virtual router forwards multicast packets for the group.
IGMP Interface Tab
Interface that has IGMP enabled.
Version 1, 2, or 3 of Internet Group Management Protocol (IGMP) running on the virtual router.
IP address of the IGMP querier on the multiaccess segment connected to the interface.
Querier Up Time
Number of seconds that the IGMP querier has been up.
Querier Expiry Time
Number of seconds remaining before the Other Querier Present timer expires.
Robustness variable of the IGMP interface.
Maximum number of groups per interface that IGMP can process simultaneously.
Maximum number of sources per interface that IGMP can process simultaneously.
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 the interface that belongs to the group.
Address of the multicast group to which the interface belongs.
IP address of the source sending multicast packets to the group.
Number of seconds this membership has been up.
Number of seconds remaining before membership expires.
Include or exclude the source. The virtual router is configured to include all traffic, or only traffic from this source (include), or traffic from any source except this one (exclude).
Number of seconds 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 virtual router learned of the RP.
ASM or SSM.
Indicates whether 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 multiaccess segment connected to the interface.
Hello interval configured (in seconds).
Interval configured for Join and Prune messages (in seconds).
PIM Assert interval configured (in seconds) for the virtual router to send Assert messages. PIM uses the Assert mechanism to initiate the election of the PIM forwarder for the multiaccess network.
Priority configured for the Designated Router on the multiaccess segment connected to the interface.
Yes or no indicates whether the interface is on a virtual router that is a bootstrap router (BSR) located at the border of an enterprise LAN.
PIM Neighbor Tab
Name of interface in the virtual router.
IP address of the PIM neighbor reachable from the interface.
Secondary IP address of the PIM neighbor reachable from the interface.
Length of time the neighbor has been up.
Length of time remaining before the neighbor expires because the virtual router is not receiving hello packets from the neighbor.
Randomly generated 32-bit value that is regenerated every time PIM forwarding is started or restarted on the interface (includes when the router itself restarts).
Designated Router priority that the virtual router 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. ...
Configure IP Multicast
Configure a virtual router on the firewall to receive and forward IP multicast traffic by configuring the interfaces: PIM on ingress and egress interfaces, and ...

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. ...
