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

acl-number: Specifies a basic ACL 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 that matches the

permit statement in the ACL is advertised as an RP served group, but the configuration that matches other

statements, like deny, does not take effect.

priority: Specifies the priority of the C-RP, in the range of 0 to 255. The default is 192. A larger value

means a lower priority.

hold-interval: Specifies a C-RP timeout timer in seconds, in the range of 1 to 65535. If you do not provide

this argument in your command, the corresponding global setting is used.

adv-interval: Specifies a C-RP-Adv interval in seconds, in the range of 1 to 65535. If you do not provide

this argument in your command, the corresponding global setting is used.

bidir: Configures the C-RP to serve multicast groups in BIDIR-PIM. Without this argument, the C-RP serves

groups in PIM-SM.

Usage guidelines

You must enable PIM-SM on the interface that you want to configure as a C-RP.

If you do not specify a group range for the C-RP, the C-RP serves all multicast groups.

If you want a device to be a C-RP for multiple group ranges, you must include these multiple group ranges

in multiple rules in the ACL that corresponds to the group-policy keyword.

If you execute this command on the same interface multiple times, the most recent configuration takes

effect.
