“Every PIM multicast group needs to be associated with the IP address of a Rendezvous Point (RP) […] For all senders to reach all receivers, it is crucial that all routers in the domain use the same mappings of group addresses to RP addresses. […] The BSR mechanism provides a way in which viable group-to-RP mappings can be created and rapidly distributed to all the PIM routers in a domain.” –rfc5059
Relevant Configuration
Enable PIM protocol
switch(config)# router pim
Configuring static address of rendezvous point for multicast group:
switch (config) # ip pim rp-address 10.10.10.10
switch (config) # ip pim vrf default rp-address 100.100.100.100 group-list 233.3.3.3/32 bidir
Configure PIM BSR candidate
switch (config) # ip pim bsr-candidate vlan 10 priority 100
Configure PIM RP candidate
switch (config) # ip pim vrf default rp-candidate ethernet 1/12 group-list 225.1.0.0/16
switch (config) # ip pim vrf default rp-candidate ethernet 1/12 bidir
