Connectivity Guide
To congure a static RP:
OS10# configure terminal
OS10(config)# ip pim rp-address 171.1.1.1 group-address 225.1.1.3/32
Designated router
Multiple PIM-SM routers can connect to a single local area network (LAN) segment. One of these routers is elected as the designated
router (DR).
The DR is elected using hello messages. Each PIM router learns about its neighbors by periodically sending a hello message out of each
PIM-enabled interface. Hello messages contain the IP address of the interface from where it is sent and a DR priority value. The router with
the greatest priority value becomes the DR. If the priority value is the same for two routers, the router with the highest IP address is the
DR. By default, the DR priority value is 1, so the IP address determines the DR.
To congure DR priority, use the following command:
OS10# configure terminal
OS10(config)# interface vlan 100
OS10(conf-if-vl-100)# ip pim dr-priority 200
