■
Use the no version to restore the default situation, in which there is no limit on
the number of MLD groups that a port can accept.
■
See multicast group port limit.
Including and Excluding Traffic
MLDv2 extends MLDv1 functionality with the ability to include or exclude specific
multicast traffic sources. That is, with MLDv2, hosts signal (S,G) pairs that they want
to include or exclude.
For hosts that cannot signal group membership dynamically, you can use the ipv6
mld static-include or ipv6 mld static-exclude command to statically include or
exclude multicast traffic, respectively.
MLDv2 is the industry-designated standard protocol for hosts to signal channel
subscriptions in SSM. For additional information about SSM, see “PIM Source-Specific
Multicast” on page 85.
ipv6 mld static-exclude
■
Use to statically exclude the MLD (S,G) membership for a host that is not capable
of dynamically signaling group membership.
■
Example
host1:boston(config-if)# ipv6 mld static-exclude 2001::1 ff0e::1
■
Use the no version to remove the static designation.
■
See ipv6 mld static-exclude.
ipv6 mld static-include
■
Use to statically include the MLD (S,G) membership for a host that is not capable
of dynamically signaling group membership.
■
Example
host1:boston(config-if)# ipv6 mld static-include 2001::1 ff0e::1
■
Use the no version to remove the static designation.
■
See ipv6 mld static-include.
Configuring Explicit Host Tracking
Explicit host tracking enables the router to explicitly track each individual host that
is joined to a group or channel on a particular multi-access network.
Explicit host tracking provides the following benefits:
