show ip bgp reg ^54$

ONLY ROUTES ORIGINATED in AS 54 and having ONLY passed DIRECTLY from 54 to
this ROUTER are shown.

show ip bgp reg ^54_

ONLY ROUTES FROM AS 54 DIRECTLY to THIS ROUTER are shown. The routes could
not have come through another AS, as AS 54 is anchored to the last AS in the
path.

You can fake these with the "local-as no-prepend replace-as" options...
