Usage Guidelines

Usage Scenario

After the bestroute as-path-ignore command is used, BGP does not compare the AS_Path lengths of routes. By default, the route with the shortest AS_Path is preferred.

Configuration Impact

After the bestroute as-path-ignore command is run, the AS_Path attribute is not used as one of the BGP route selection rules.
