Parameters
interface-type interface-number: Specifies an interface, the IP address of which will be
advertised as a C-RP address.
acl-number: Basic ACL number, in the range of 2000 to 2999. This ACL defines a range
of multicast groups the C-RP is going to serve, rather than defining a filtering rule. Any
group range matching 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
of this argument means a lower priority.
hold-interval: C-RP timeout time, in seconds. The effective range is 1 to 65,535. If you
do not provide this 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 provide 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:
z If you do not specify a group range for the C-RP, the C-RP will serve all multicast
groups.
z If you wish a router to be a C-RP for multiple group ranges, you need to include
these multiple group ranges in multiple rules in the ACL corresponding to the
group-policy keyword.
z If you carry out this command repeatedly on the same interface, the last
configuration will take effect.
