neighbor local-as
Use the neighbor local-as command to configure BGP to advertise the local-
as instead of the router’s own AS in the routes advertised to the neighbor.
Syntax
neighbor { ip-address | ipv6-address [ interface interface-name ] |
autodetect
interface vlan vlan-id } local-as as-number no-prepend replace-as
no neighbor { ip-address | ipv6-address [ interface interface-name ] |
autodetect
interface interface-id } local-as
• ip-address — The neighbor’s IPv4 address.
•
ipv6-address [ interface interface-id ] — The neighbor’s IPv6 address. If
the neighbor’s IPv6 address is a link local address, the local interface must
also be specified.
•
autodetect interface interface-id — The VLAN routing interface on which
the neighbor’s link local IPv6 address is auto detected.
•
local-as as-number — The AS number to advertise as the local AS in the
AS PATH sent to the neighbor.
•
no-prepend — The local-as is not prepended in the AS PATH received in
the updates from this neighbor.
•
replace-as — Replace the router’s own AS with the local-as in the AS
PATH sent to the neighbor.
Default Configuration
No local-as is configured for any peer.
