If the mld group-policy command has been configured on an interface, the interface cannot receive
•
report messages that fail to pass filtering.
Solution
1.
Use the display mld interface command to verify that the networking, interface connections, and IP
address configuration are correct. If no information is output, the interface is in an abnormal state.
The reason is that you have configured the shutdown command on the interface, that the interface
is not properly connected, or that the IPv6 address configuration is not correctly done.
2.
Use the display current-configuration command to verify that the IPv6 multicast routing is enabled.
If not, use the multicast ipv6 routing-enable command in system view to enable IPv6 multicast
routing. In addition, enable MLD on the corresponding interface.
3.
Use the display mld interface command to verify that the MLD 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 restrict the host from joining IPv6 multicast group G. If an IPv6 ACL is configured to
restrict the host from joining IPv6 multicast group G, the ACL must be modified to allow IPv6
multicast group G to receive report messages.
Membership information is inconsistent on routers on the same
subnet
Symptom
The MLD routers on the same subnet have different membership information.
Analysis
A router running MLD maintains multiple parameters for each interface, and these parameters
•
influence one another, forming very complicated relationships. Inconsistent MLD interface
parameter configurations for routers on the same subnet will surely result in inconsistent MLD
memberships.
•
Two MLD versions are available. Although routers running different MLD versions are compatible
with hosts, all routers on the same subnet must run the same MLD version. Inconsistent MLD versions
running on routers on the same subnet will also lead to inconsistent MLD memberships.
Solution
1.
Use the display current-configuration command to verify the MLD configuration information on the
interface.
2.
Use the display mld interface command on all routers on the same subnet to check the MLD timers
for inconsistent configurations.
3.
Use the display mld interface command to verify that the routers are running the same MLD
version.
