between trees. PIM-SM uses a bootstrap router (BSR), which advertises information to other multicast routers about the RP. In a given network, a set of routers can be administratively enabled as candidate bootstrap routers. If it is not apparent which router should be the BSR, the candidates flood the domain with advertisements. The router with the highest priority is elected. If all the priorities are equal, then the candidate with the highest IP address becomes the BSR. PIM-SM is defined in RFC 4601.

The following example describes how to configure and use PIM-SM. In this case, set the switch B,C,D as RP-candidate and BSR-candidate. Switch B will become the BSR because it has the highest priority. Switch D will become the RP after RP election.

CLI: Configure PIM-SM

PIM-SM on Switch A

1.Enable IP routing on the switch.

(Netgear Switch)#configure

(Netgear Switch) (Config)#ip routing

2.Enable PIM-SM on the switch.

(Netgear Switch) (Config)#ip pim sparse

3.Enable IP multicast forwarding on the switch.

(Netgear Switch) (Config)#ip multicast

4.Enable RIP to build a unicast IP routing table.

(Netgear Switch) (Config)#interface 1/0/1 (Netgear Switch) (Interface 1/0/1)#routing

(Netgear Switch) (Interface 1/0/1)#ip address 192.168.2.2 255.255.255.0 (Netgear Switch) (Interface 1/0/1)#ip rip
