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 from each PIM-enabled interface. Hello messages contain the interface IP address from where it is sent and a DR priority value. The router with the highest 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 configure DR priority, use the following command: OS10# configure terminal OS10(config)# interface vlan 100 OS10(conf-if-vl-100)# ip pim dr-priority 200 PIM commands clear ip pim tib Clears PIM tree information from the PIM database. Syntax clear ip pim [vrf vrf-name] tib Parameters vrf vrf-name-Enter the keyword vrf, then the name of the VRF. Default None Command Mode EXEC PRIVILEGE Usage Information When you run this command on a node, it deletes: • All the multicast routes from the PIM tree information base (TIB) • The entire multicast route table and all the entries in the data plane With VLT multicast routing, when you run this command on a local VLT node, it deletes: • All the multicast routes from the local PIM TIB • All the local mroute entries in the data plane • The synchronized mroute entries from the VLT peer node Example OS10# clear ip pim vrf vrf1 tib Supported Releases 10.4.3.0 or later ip multicast-routing Enables IP multicast forwarding. Syntax Parameters ip multicast-routing [vrf vrf-name] vrf vrf-name-Enter the keyword vrf, then the name of the VRF. Multicast 779
