l preferred: indicates that the static RP takes precedence. The C-RP is configured in the
network at the same time. After preferred is set, switchs prefer the static RP. Otherwise,
switchs prefer the C-RP.
Multiple static RPs can be configured by using this command repeatedly, but the same ACL
cannot correspond to multiple static RPs. If the ACL is not configured, only one static RP can
be configured.
NOTE
The same static-rp command must be used on all switchs in the PIM-SM domain.

13.3.6 (Optional) Configuring a Dynamic RP
In an IPv6 PIM-SM domain, you can select several PIM devices and configure C-RPs on the
devices. Then, the 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.
Context
CAUTION
This configuration is applicable only to the dynamic RP. If the dynamic RP is not used in this
network, this configuration is not necessary.
Do as follows on switchs that may become RP in the PIM-SM domain:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
pim-ipv6
The PIM-IPv6 view is displayed.
Step 3 Run:
c-rp ipv6-address [ advertisement-interval interval | group-policy { basic-acl6-
number | acl6-name acl6-name } |holdtime interval | priority priority-value ]
*
The C-RP is configured.
The parameters of this command are explained as follows:
l ipv6-address: specifies the IPv6 address of the interface where the C-RP resides. PM-SM
must be enabled on that interface.
