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. |
