● replace-as—(Optional) Enter so that globally configured AS values are not prepended to the
AS_PATH attribute.
Default Disabled
Command Mode ROUTER-NEIGHBOR or ROUTER-TEMPLATE
Usage
Information
Facilitates the BGP network migration operation and allows you to maintain existing AS numbers. The no
version of this command resets the value to the default.
This command is supported only for external BGP (eBGP) autonomous system migration, and it is not
supported for internal BGP (iBGP) autonomous system migration.
After configuring the replace-as option, clear the BGP session.
The no local-as command deletes the local-as configuration. The no local-as no-prepend
command removes both local and globally-configured AS numbers from the AS_PATH attribute and
leaves the local-as local-as configuration intact.

ROUTER-CONFIG-VRF sub mode using the following commands:
1. Enter the ROUTER BGP mode using the router bgp as-number command.
2. From the ROUTER BGP mode, enter the ROUTER BGP VRF mode using the vrf vrf-name
command.
