429 Parameter AS Number Synchronization Overlap Router Policy Default Local Preference Advertisement of Non-BGP Routes Always Compare MED Description This parameter specifies the autonomous system to which the switch is connected, which is a read-only field. The synchronization between IGP and BGP can be ensured by enabling this field. This parameter represents the policy for handling overlapping routes. When an overlapping route is received, depending upon the configured policy, either the less-specific routes or most-specific routes or both are installed in the RIB tree. This parameter sets a preference value for the autonomous system path. You can choose to advertise even the external non-BGP routes by enabling this feature. By enabling this feature, you can choose to always compare the MED values of paths from different neighbors for the same prefix, for choosing the best path.
