+        <div class="card-description">Junos OS 25.4R1 adds as-path-replace, a routing policy action for rewriting the BGP AS_PATH. The action takes the AS numbers to look for, or the keyword private to cover every private AS number, and replaces each match with the session&#x27;s local AS. Operators can use it to keep private AS numbers out of the default-free zone, retire an AS number after an acquisition, or even out path lengths for load sharing. Junos already has several ways to change the AS_PATH, each built for a narrower case. Prepending is a policy action on import and export, but it can only add to the path. as-override and remove-private also change numbers already in the path, but they have narrower scopes: they apply to every route advertised to a peer, replacing the peer&#x27;s AS with the local AS (as-override) or removing private AS numbers (remove-private). as-path-replace is the first action that lets you select specific AS numbers to rewrite, replacing each match with the session&#x27;s local AS, for the routes a policy term selects, on import as well as export. That flexibility matters because routers use the AS_PATH to detect loops and compare paths, so rewriting it changes how other networks treat the route.</div>
