The set protocols bgp neighbor as-override command overrides AS number of the originating router with the local AS number.
The delete protocols bgp neighbor as-override command restores the default setting.
Command Syntax
set protocols bgp [vrf <vrf-name>] {ipv4 unicast|ipv4 labeled-unicast|ipv6 unicast|ipv6 labeled-unicast} {neighbor <ip>| peer-group <peer-group> |interface <interface>} as-override
delete protocols bgp [vrf <vrf-name>] {ipv4 unicast|ipv4 labeled-unicast|ipv6 unicast|ipv6 labeled-unicast} {neighbor <ip>| peer-group <peer-group> |interface <interface>} as-override
Parameter
Parameter | Description |
vrf <vrf-name> | Optional. Specifies a VRF name. The value is a string. It’s a user-defined VRF set by the command set ip vrf <vrf-name> [description <string>]. |
| {ipv4 unicast|ipv4 labeled-unicast|ipv6 unicast|ipv6 labeled-unicast} | Specifies the type of the address family. |
| neighbor <ip> | Specifies the IP address of a peer. |
| peer-group <peer-group> | Specifies a peer group. |
| interface <interface> | Specifies an interface for BGP connection. |
Usage Guidelines
Usually this configuration is used in PEs (Provider Edge) to replace the incoming customer AS number so the connected CE (Customer Edge) can use the same AS number as the other customer sites. This allows customers of the provider network to use the same AS number across their sites.
This command is only allowed for eBGP peers.
Example
• This example overrides AS number of the originating router with the local AS number.
