Command Mode
Address Family-vrf mode
Usage
BGP normally ignores the routes from the same AS. This command is used to override the customer‘s ASN in
BGP, so that the customer CE accepts and installs routes from the same AS.
Typically, this command is used when Customer Edge (CE) routers have the same ASN in some or all sites.
As per BGP requirement, a BGP speaker rejects a route that has the same ASN as itself, in the AS_PATH
attribute. Thus the CE routers having the same ASN do not accept routes from each other. Configuring the
neighbor as-override command on the PE router removes the CE neighbor’s ASN from the AS_PATH attribute
allowing CE routers with the same ASN to accept routes from each other.
Examples
Switch(config-router)# address-family ipv4 vrf VRF_A
Switch(config-router-af)# neighbor 10.10.0.1 as-override
