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 command in user view.
Task Command
Display MLD group information.
display mld group [ ipv6-group-address | interface interface-type
interface-number ] [ static | verbose ]
Display MLD information. display mld interface [ interface-type interface-number ] [ verbose ]
Remove all the dynamic group
entries of a specified MLD group
or all MLD groups.
reset mld group { all | interface interface-type interface-number { all |
ipv6-group-address [ prefix-length ] [ ipv6-source-address
[ prefix-length ] ] } }
NOTE:
The reset mld group command cannot remove static MLD group entries.
MLD configuration examples
Network requirements
VOD streams are sent to receiver hosts in multicast. Receiver hosts of different organizations form stub
networks N1 and N2. Host A and Host C are multicast receiver hosts 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.
