Inconsistent Membership Information On The Routers On The Same Subnet - HP MSR2003 Configuration Manual

2. Use the display current-configuration command to verify that multicast routing is enabled. If it is not
enabled, use the multicast routing command in system view to enable IP multicast routing. In
addition, verify that IGMP is enabled on the associated interfaces.
3. Use the display igmp interface command to verify that the IGMP version on the interface is lower
than that on the host.
4. Use the display current-configuration interface command to verify that no ACL rule has been
configured to filter out the reports sent by the host to the multicast group G.
5. If the problem persists, contact HP Support.
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.
Although IGMP routers are partially compatible with hosts that separately run different IGMP
•
versions, all routers on the same subnet must run the same IGMP version. 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.
Use the display igmp interface command to verify that all the routers on the same subnet are

running the same IGMP version.
