NETGEAR 8800 Chassis Switch CLI Manual Default Disabled. BGP does not automatically originate and advertise default routes to BGP neighbors. Usage Guidelines This command can be successfully executed at any time, irrespective of whether local BGP or the remote BGP peer is enabled or disabled. The default route or routes are created regardless of whether or not there are matching entries in the IP route table. When a BGP neighbor is added to a peer group, it does not inherit the default route origination configuration from the peer group. Also, default route origination for a neighbor and the associated peer group can be different. If a policy is configured and specified in the command, a default route can be originated only if there is a route in the local BGP RIB that matches the policy's match rules. The default route's attribute can be modified using the same policy file by including statements in the set block of the policy. Example The following command enables the origination and advertisement of default routes for IPv4 unicast traffic for all BGP peer nodes: enable bgp neighbor all originate-default enable bgp neighbor remove-private-AS-numbers enable bgp neighbor [ | all] remove-private-AS-numbers Description Enables the removal of private AS numbers from the AS path in route updates sent to EBGP peers. Syntax Description remoteaddr all Specifies an IP address of a BGP neighbor. Specifies all neighbors. Default Disabled. Usage Guidelines Private AS numbers are AS numbers in the range 64512 through 65534. You can remove private AS numbers from the AS path attribute in updates that are sent to external BGP (EBGP) neighbors. Possible reasons for using private AS numbers include: Chapter 25.
