bestroute router-id-ignore (BGP-IPv4 multicast address family view)

Function

The bestroute router-id-ignore command configures MBGP to ignore the router ID when selecting the optimal route.

Usage Guidelines

Usage Scenario

When receiving multiple routes with the same prefix from multiple peers, MBGP needs to select an optimal route from these routes. Configuring MBGP not to compare the router IDs contained in routes when selecting the optimal route can prevent unnecessary route switching.

Configuration Impact

When selecting the optimal route, MBGP does not compare the router IDs and peer IP addresses contained in routes after the bestroute router-id-ignore command is run.

Example

# Configure MBGP not to compare the router IDs and peer IP addresses contained in routes when selecting the optimal route.
