Huawei quidway s7700 - Optional) Configuring a Dynamic RP

l basic-acl-number | acl-name acl-name: specifies the ACL. The ACL defines the range of
the multicast group served by the static RP. When the range of multicast groups that multiple
static RPs serve overlaps, the static RP with the largest IP address functions as the RP.
l preferred: indicates the preference of the static RP. If the C-RP is configured in the network
at the same time, the switch prefers the RP statically specified after preferred is used.
Otherwise, C-RP is preferred.

6.3.5 (Optional) Configuring a Dynamic RP
In a PIM-SM domain, you can select several PIM devices and configure C-RPs on the devices.
Then, an RP is elected from these C-RPs. The C-BSRs should also be configured and a BSR is
elected from these C-BSRs. The BSR is responsible for collecting and advertising the C-RP
information on the network. The system supports the auto-RP listening function.
Context
CAUTION
The configuration is applicable only to the dynamic RP. If you want to use the static RP in the
network, skip the configuration.
Do as follows on the switch that may become RP in the PIM-SM area:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
pim [ vpn-instance vpn-instance-name ]
The PIM view is displayed.
Step 3 Run:
c-rp interface-type interface-number [ group-policy { basic-acl-number | acl-name
acl-name } | priority priority | holdtime hold-interval | advertisement-interval
adv-interval ] *
The C-RP is configured.
l interface-type interface-number: specifies the interface where the C-RP resides. The
interface must be configured with PIM-SM.
l group-policy { basic-acl-number | acl-name acl-name }: specifies the multicast group
permitted by ACL and served by the C-RP. By default, C-RP serves all multicast groups.
l priority priority: specifies the priority for electing C-RP. The greater is the value, the lower
is the priority. By default, it is 0.
In the RP election, the C-RP with the highest priority wins. In case of the same priority, the
hash function is used and the C-RP with the greatest hash value wins. In case of the same
priority and the same hash value, the C-RP with the highest IP address wins.
