neighbor remove-private-as

Configures a device to remove private autonomous system numbers (ASNs) from UPDATE messages that the device sends to a neighbor.

Syntax

neighbor { ip-address | ipv6-address | peer-group-name } remove-private-as

no neighbor { ip-address | ipv6-address | peer-group-name } remove-private-as

Parameters

ip-address: IPv4 address of the neighbor
ipv6-address: IPv6 address of the neighbor
peer-group-name: Peer group name configured by the neighbor peer-group-name command.

Modes

BGP configuration mode

BGP address-family IPv4 unicast VRF configuration mode

BGP address-family IPv6 unicast VRF configuration mode

Usage Guidelines

The device will remove ASNs 64512 through 65535 (the well-known BGP4 private ASNs) from the AS-path attribute in UPDATE messages that the device sends to a neighbor.

The no form of the command restores the default so that private ASNs are not removed from UPDATE messages sent to a neighbor by a device.

Examples

The following example removes private ASNs globally.

device# configure terminal
device(config)# router bgp
device(config-bgp-router)# neighbor 10.11.12.13 remove-private-as

The following example removes private ASNs for VRF instance "red".

device# configure terminal
device(config)# router bgp
device(config-bgp-router)# address-family ipv6 unicast vrf red
device(config-bgp-ipv6u-vrf)# neighbor 10.11.12.13 remove-private-as
