Table B-17 BGP-4 Received Path Attribute Table (continued)

Field	Description
bgp4PathAttrASPathSegment	The sequence of AS path segments. Each AS path segment is represented by a triple
	<type, length, value>.
	The type is a 1-octet field which has two possible values:
	• AS_SET: unordered set of ASs a route in the UPDATE messages has traversed.
	• AS_SEQUENCE: ordered set of ASs a route in the UPDATE messages has traversed.
	The length is a 1-octet field containing the number of ASs in the value field. The value
	field contains one or more AS numbers. Each AS is represented in the octet string as a
	pair of octets according to the following algorithm:
	• first-byte-of-pair = ASNumber / 256;
	• second-byte-of-pair = ASNumber & 255;
bgp4PathAttrNextHop	The address of the border router that should be used for the destination network.
bgp4PathAttrMultiExitDisc	This metric discriminates between multiple exit points to an adjacent AS, ranging from 1
	to 2147483647. A value of -1 indicates the absence of this attribute.
bgp4PathAttrLocalPref	The originating BGP4 speaker's degree of preference for an advertised route, ranging
	from 1 to 2147483647. A value of -1 indicates the absence of this attribute.
bgp4PathAttrAtomicAggregate	Whether or not the local system has selected a less specific route without selecting a
	more specific route.
bgp4PathAttrAggregatorAS	The AS number of the last BGP4 speaker that performed route aggregation, ranging
	from 0 -65535. A value of zero (0) indicates the absence of this attribute.
bgp4PathAttrAggregatorAddr	The IP address of the last BGP4 speaker that performed route aggregation. A value of
	0.0.0.0 indicates the absence of this attribute.
bgp4PathAttrCalcLocalPref	The degree of preference calculated by the receiving BGP4 speaker for an advertised
	route, ranging from 1 to 2147483647. A value of -1 indicates the absence of this
	attribute.
bgp4PathAttrBest	An indication of whether or not this route was chosen as the BGP4 route.
bgp4PathAttrUnknown	One or more path attributes not understood by this BGP4 speaker. Range: 0-255. Size
	zero (0) indicates the absence of such attribute(s). Octets beyond the maximum size, if
	any, are not recorded by this object.
