Troubleshooting Mld; No Member Information Exists On The Receiver-Side Router; Inconsistent Membership Information On The Routers On The Same Subnet - HP VSR1000 Configuration Manual

Troubleshooting MLD

No member information exists on the receiver-side router

Symptom
When a host sends a message to announce that it is joining IPv6 multicast group G, no member
information of multicast group G exists on the immediate router.
Solution
To resolve the problem:
Use the display mld interface command to verify that the networking, interface connections,
1.
and IP address configuration are correct.
Use the display current-configuration command to verify that the IPv6 multicast routing is
2.
enabled. If it is not enabled, use the ipv6 multicast routing command in system view to enable
IPv6 multicast routing. In addition, verify that MLD is enabled on the associated interfaces.
Use the display mld interface command to verify that the MLD version on the interface is
3.
lower than that on the host.
Use the display current-configuration interface command to verify that no IPv6 multicast
4.
group policies have been configured to filter MLD reports for IPv6 multicast group G.
If the problem persists, contact Hewlett Packard Enterprise Support.
5.
Inconsistent membership information on the routers on the
same subnet
Symptom
Different memberships are maintained on different MLD routers on the same subnet.
Solution
To resolve the problem:
Use the display current-configuration command to verify the MLD information on the
1.
interface. Make sure MLD interface parameter configurations for routers on the same subnet
are the same.
Use the display mld interface command on all routers on the same subnet to check the MLD
2.
timers for inconsistent configurations.
Use the display mld interface command to verify that all routers are running the same MLD
3.
version.
If the problem persists, contact Hewlett Packard Enterprise Support.
