Example console(config-router)#neighbor 10.130.14.55 remote-as 10 neighbor remove-private-as Use the neighbor remove-private-as command to remove private AS numbers when advertising IPv4 routes to an external peer. To stop removing private AS numbers, use the no form of this command. Syntax neighbor { ip-address | ipv6-address [interface vlan vlan-id]} removeprivate-as [ all replace-as ] no neighbor { ip-address | ipv6-address [interface vlan vlan-id]} removeprivate-as • ip-address - The neighbor's IPv4 address. • ipv6-address- The neighbor's IPv6 address. If the neighbor's IPv6 address is a link local address, the local interface must also be specified. • interface vlan vlan-id - The local interface/VLAN ID over which the IPv6 neighbor can be reached. Range 1-4093. • all replace-as - (Optional) To retain the original AS path length, replace each private AS number with the local AS number. Default Configuration Private AS numbers are not removed by default. Command Mode BGP Router Configuration mode User Guidelines This command can only be applied to external peers. Private AS numbers are removed or replaced whether or not the original AS path includes any nonprivate AS numbers. The AS path advertised to the external peer always includes at least one instance of the local AS number; therefore, removing private AS numbers never results in advertisement of an empty AS_PATH attribute. AS numbers from 64512 to 65535 inclusive are considered private. Although 65535 is a reserved ASN and not technically part of the private Layer 3 Routing Commands 1319
