When a router running SR OS Release 15.0.R4 or later receives a BGP route of any AFI/SAFI, with the LLGR_STALE community, the decision process considers the route less preferred than any valid, non-stale LLGR route for that NLRI. This logic applies even if the router is not configured as long-lived. If a route with an LLGR_STALE community is selected as the best path, then it is advertised to peers according to the configuration of the advertise-stale-to-all-neighbors command; if this command is absent (or the long-lived context is absent), then the route is advertised only to peers that advertised the LLGR capability.
