defining a filtering rule. Any IPv6 multicast group range that matches the permit
statement in the ACL will be advertised as an RP served group, while
configurations matching other statements like deny will not take effect.
priority: Priority of the C-RP, in the range of 0 to 255 and defaulting to 0. A larger
value means a lower priority.
hold-interval: C-RP timeout time, in seconds. The effective range is 1 to 65,535. If
you do not include provide argument in your command, the corresponding global
setting will be used.
adv-interval: C-RP-Adv interval in seconds, with an effective range of 1 to 65,535.
If you do not include this argument in your command, the corresponding global
setting will be used.
Description Use the
c-rp command to configure the specified interface as a C-RP.
Use the undo c-rp command to remove the related C-RP configuration.
No C-RPs are configured by default.
Note that:
■ If you do not specify an IPv6 multicast group range for the C-RP, the C-RP will
serve all IPv6 multicast groups.
■ If you wish a router to be a C-RP for multiple group ranges, you need to include
these group ranges in multiple rules in the IPv6 ACL corresponding to the
group-policy keyword.
■ If you carry out this command repeatedly on the same interface, the last
configuration will take effect.
