Multicast Tab

The following table describes the virtual router’s Runtime Stats for IP multicast.

Multicast Runtime Stats	Description
FIB Tab
Group	Route entry in the forwarding information base (FIB); multicast group address to which the virtual router will forward packets.
Source	Source address of multicast packets for the group.
Incoming Interfaces	Interfaces where multicast packets for the group arrive.
Outgoing Interfaces	Interfaces out which the virtual router forwards multicast packets for the group.
IGMP Interface Tab
Interface	Interface that has IGMP enabled.
Version	Version 1, 2, or 3 of Internet Group Management Protocol (IGMP) running on the virtual router.
Querier	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	Robustness variable of the IGMP interface.
Groups Limit	Maximum number of groups per interface that IGMP can process simultaneously.
Sources Limit	Maximum number of sources per interface that IGMP can process simultaneously.
Immediate Leave	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
Interface	Name of the interface that belongs to the group.
Group	Address of the multicast group to which the interface belongs.
Source	IP address of the source sending multicast packets to the group.
Up Time	Number of seconds this membership has been up.
Expiry Time	Number of seconds remaining before membership expires.
Filter Mode	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).
Exclude Expiry	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
Group	IP address of the group mapped to a Rendezvous Point.
RP	IP address of Rendezvous Point for the group.
Origin	Indicates where the virtual router learned of the RP.
PIM Mode	ASM or SSM.
Inactive	Indicates whether the mapping of the group to the RP is inactive.
PIM Interface Tab
Interface	Name of interface participating in PIM.
Address	IP address of the interface.
DR	IP address of the Designated Router on the multiaccess segment connected to the interface.
Hello Interval	Hello interval configured (in seconds).
Join/Prune Interval	Interval configured for Join and Prune messages (in seconds).
Assert Interval	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.
DR Priority	Priority configured for the Designated Router on the multiaccess segment connected to the interface.
BSR Border	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
Interface	Name of interface in the virtual router.
Address	IP address of the PIM neighbor reachable from the interface.
Secondary Address	Secondary IP address of the PIM neighbor reachable from the interface.
Up Time	Length of time the neighbor has been up.
Expiry Time	Length of time remaining before the neighbor expires because the virtual router is not receiving hello packets from the neighbor.
Generation ID	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).
DR Priority	Designated Router priority that the virtual router received in the last PIM hello message from this neighbor.
