Configuring a
PIM RP Candidate
Use the Routing Protocol > PIM > SM (RP Candidate) page to configure the switch
to advertise itself as a Rendezvous Point (RP) candidate to the bootstrap router
(BSR).
Command Usage
â—† When this router is configured as an RP candidate, it periodically sends PIMv2
messages to the BSR advertising itself as a candidate RP for the specified group
addresses. The IP address of the designated VLAN is sent as the candidate’s RP
address. The BSR places information about all of the candidate RPs in
subsequent bootstrap messages. The BSR uses the RP-election hash algorithm
to select an active RP for each group range. The election process is performed
by the BSR only for its own use. Each PIM-SM router that receives the list of RP
candidates from the BSR also elects an active RP for each group range using the
same election process.
â—† The election process for each group is based on the following criteria:
â–
Find all RPs with the most specific group range.
â–
Select those with the highest priority (lowest priority value).
