R2511-HP MSR Router Series IP Multicast Command Reference(V5)

284
Default command level
2: System level
Parameters
limit: Specifies the maximum number of IPv6 multicast groups that an interface can join.
Usage guidelines
This command is effective only on dynamically joined IPv6 multicast groups but not statically joined IPv6
multicast groups.
If the configured limit value is smaller than the number of the existing IPv6 multicast groups on the current
interface, the system does not automatically remove the IPv6 multicast groups in excess. To bring this
configuration into effect in this case, you need to use the reset mld group command to clear the IPv6
multicast groups information manually.
For a device that supports both MLD snooping and MLD, you can also use the mld-snooping group-limit
command to limit the number of IPv6 multicast groups that an interface can join. However, if you
configure the limit both in a VLAN and on a VLAN interface of this VLAN by using these two commands,
inconsistencies might exist between Layer 2 and Layer 3 table entries. Therefore, HP recommends you to
configure the limit only in the VLAN interface.

mld group-policy
Use mld group-policy to configure an IPv6 multicast group filter on the current interface to control the IPv6
multicast groups that the hosts on the current interface can join.
Use undo mld group-policy to remove the configured IPv6 multicast group filter.

mld group-policy acl6-number [ version-number ]
