The neighbor local-as CLI is enhanced to hide and replace the AS number of the remote routers not connected to external peer. Two new options ‘no-prepend’ and ‘replace-as’ have been added. These options replace the AS number with an alternate AS number in the AS_PATH and BGP OPEN message. Hence, the AS of the remote router is unknown to the respective neighbor peer.

For more information on Hide the Remote AS using the neighbor local-as Command refer to OcNOS Key Feature document, Release 6.4.1.
