The remote AS number used on this session. If bgpPeerConfAltLocalAs is set to a non-zero value, and if this is an IBGP peer, then the remote peer might have advertised one of two AS numbers (bgpPeerRemoteAs or bgpPeerConfAltLocalAs). This field reports which AS number was advertised by the remote peer. If bgpPeerConfAltLocalAs is zero, then the AS number advertised by the remote peer (and reported in this this field) must equal bgpPeerRemoteAs. For dynamic peers there is no bgpPeerConfAltLocalAs field so the remote AS number used on the session is always bgpPeerRemoteAs. If the bgpPeerStatusState is not 'established', then this field is zero.
