Usage Guidelines

Usage Scenario

After the bestroute as-path-ignore command is used, BGP does not compare the AS path attributes of routes (including the AS_Path length and content).

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.
