Configuring PIM Designated Router Election on Point-to-Point Links
To comply with the latest PIM drafts, enable designated router (DR) election on all PIM interfaces, including point-to-point (P2P) interfaces. (DR election is enabled by default on all other interfaces.) One of the two routers might join a multicast group on its P2P link interface. The DR on that link is responsible for initiating the relevant join messages.
To enable DR election on point-to-point interfaces:
- On both point-to-point link routers, configure the router
globally or in the routing instance. This example shows the configuration
for the routing instance.[edit routing-instances PIM.master protocols pim]user@host# set dr-election-on-p2p
- Verify the configuration by checking the State field in the output of the show pim interfaces command. The possible values for the State field are DR, NotDR, and P2P. When a point-to-point link interface is elected to be the DR, the interface state becomes DR instead of P2P.
- If the show pim interfaces command continues
to report the P2P state, consider running the restart routing command on both routers on the point-to-point link. Then recheck
the state.
Caution: Do not restart a software process unless specifically asked to do so by your Juniper Networks customer support representative. Restarting a software process during normal operation of a routing platform could cause interruption of packet forwarding and loss of data.
