O CONFIGURE RP
RP is the root of shared tree. Data flows from source to RP on SPT, and RP sends
data on RPT. Each group can have different RP. There are various ways to learn/
configure RP for a group.
OmniAccess 5740 USG supports static RP and dynamic RP (learning RP using
BSR protocol).

Command (in CM) Description
ip pim rp-address <ip-address>
[override]
This command is used to configure the
RP router address for all multicast
groups.
Override keyword can be used to give
preference to static RP over dynamic RP.
Command (in CM) Description
ip pim rp-candidate
<interface-name> [group-list
{<access-list-name>|<1-99>}]
This command is used to configure the
PIM router as RP candidate. RP uses
specified interface address.
Group list is used to specify access-list,
which contains the multicast group for
which RP candidate is being configured.
BSR selects the RP with the highest
priority.
If multiple routers are candidate RP for
same group and having same priority,
then BSR calculates the hash value, and
with the highest hash value becomes RP.
If more than one RP has the same hash
value, the RP with the highest IP address
is chosen.
