Troubleshooting Mld; No Member Information On The Receiver-Side Router - HP 4800G Series Configuration Manual

[SwitchA-Vlan-interface100] pim ipv6 dm
[SwitchA-Vlan-interface100] quit
# Enable IPv6 multicast routing on Switch B, MLD proxying on VLAN-interface 100, and MLD on
VLAN-interface 200.
<SwitchB> system-view
[SwitchB] multicast ipv6 routing-enable
[SwitchB] interface vlan-interface 100
[SwitchB-Vlan-interface100] mld proxying enable
[SwitchB-Vlan-interface100] quit
[SwitchB] interface vlan-interface 200
[SwitchB-Vlan-interface200] mld enable
[SwitchB-Vlan-interface200] quit
3) Verify the installation
Use the display mld interface command to view the MLD configuration and operation information on
an interface. For example,
# View MLD configuration and operation information on VLAN-interface 100 of Switch B.
[SwitchB] display mld interface vlan-interface 100 verbose
Vlan-interface100(2001::2):
MLD proxy is enabled
Current MLD version is 1
Multicast routing on this interface: enabled
Require-router-alert: disabled
Use the display mld group command to view MLD multicast group information. For example,
# View the MLD multicast group information on Switch A.
[SwitchA] display mld group
Total 1 MLD Group(s).
Interface group report information
Vlan-interface100(2001::1):
Total 1 MLD Groups reported
Group Address
ff3e::101
As shown above, the MLD reports sent from the hosts are forwarded to Switch A through the proxy
interface, VLAN-interface 100 of Switch B.

Troubleshooting MLD

No Member Information on the Receiver-Side Router

Symptom
When a host sends a message for joining IPv6 multicast group G, there is no member information of
multicast group G on the immediate router.
Analysis
The correctness of networking and interface connections and whether the protocol layer of the
interface is up directly affect the generation of IPv6 group member information.
