Inconsistent membership information on the routers on the same
subnet
Symptom
Different memberships are maintained on different IGMP routers on the same subnet.
Analysis
•
A router running IGMP maintains multiple parameters for each interface. Inconsistent IGMP
interface parameter configurations for routers on the same subnet will result in inconsistency of
memberships.
•
In addition, although IGMP routers are partially compatible with hosts that separately run different
versions of IGMP, all routers on the same subnet must run the same version of IGMP. Inconsistent
IGMP versions running on routers on the same subnet leads to inconsistency of IGMP memberships.
Solution
1.
Use the display current-configuration command to verify the IGMP information on the interfaces.
2.
Use the display igmp interface command on all routers on the same subnet to verify the
IGMP-related timer settings. Make sure the settings are consistent on all the routers.
3.
Use the display igmp interface command to verify that all the routers on the same subnet are
running the same IGMP version.
