Table 63. IGMP Cache Table Fields
Field
Description
IP Multicast Address
Identifies the IP address of the multicast group.
IGMP Interface
Indicates the interface on which the IP multicast group is configured.
Cache Status
Indicates whether the multicast group on the interface is active, not in
service, not ready, create and go, create and wait, or destroyed.
Local Membership
Indicates whether a router is a member of the group. The SSR is
never a member of a group.
Member Since
Indicates how long ago the SSR joined the multicast group address.
A 0 signifies that the SSR is not a member of the group.
Last Reported Member
Identifies the IP address of the source that sent the SSR the last mem-
bership report for the multicast group on the interface identified in
the IGMP Interface field. An IP address of 0.0.0.0 signifies that the
SSR has not received a membership report on the multicast group's
interface.
Cache Expiry Time
Indicates the minimum amount of time remaining before the entry
will be deleted from the IGMP Cache table.
Time Before Expiry
Indicates how much longer the SSR will assume that there are no
IGMP version 1 members on the IP subnetwork attached to the mul-
ticast group's interface. If this time is greater than 0, any version 2
IGMP messages the SSR receives on the interface are ignored.
SSR resets this field whenever it receives a version 1 IGMP member-
ship report on the interface.
