This is a string depicting the autonomous system path to this network which was received from the peer which advertised it. If bgpRmEntAsSize is four-octet and the peer does not support four octet AS numbers this string represents the AS_PATH formed by combining the AS_PATH and AS4_PATH attributes as detailed in RFC 4893. Two-octet AS numbers appear as four-octet numbers by adding two bytes of zero padding. The format of the string is simply the AS_PATH attribute. It can be converted to a more readable format by the management agent.
