Displaying And Maintaining Mld; Mld Configuration Examples; Network Requirements - HP 6125XLG Configuration Manual

With MLD fast-leave processing enabled, after receiving an MLD done message from a host, the MLD
querier sends a leave notification to the upstream immediately without first sending MLD
multicast-address-specific queries. This reduces leave latency and preserves the network bandwidth.
To enable MLD fast-leave processing:
Step
1. Enter system view.
2. Enter interface view.
3. Enable MLD fast-leave
processing.

Displaying and maintaining MLD

CAUTION:
The reset mld group command might cause IPv6 multicast data transmission failures.
Execute display commands in any view and reset commands in user view.
Task
Display MLD group information.
Display MLD information.
Remove all the dynamic group
entries of a specified MLD group
or all MLD groups.
NOTE:
The reset mld group command cannot remove static MLD group entries.

Network requirements

As shown in
organizations form stub networks N1 and N2. Host A and Host C are multicast receivers in N1 and N2,
respectively.
MLDv1 runs between Switch A and N1, and between the other two switches (Switch B and Switch C) and
N2. Switch A acts as the MLD querier in N1. Switch B acts as the MLD querier in N2 because it has a
lower IPv6 address.
The hosts in N1 can join only the IPv6 multicast group FF1E::101. The hosts in N2 can join any IPv6
multicast groups.
