1. Allowing for a peer in future implementations to

2. Allow for extensions which extend the NLRI field

this is RFC 3107 - Carrying MPLS labels in BGP."

DESCRIPTION
|
|
"In order to provide a canonicalized form of the BGP-4
|
|
AS_PATH along with the human-readable
|
|
bgp4V2NlriAsPathString, which may be truncated, this object
|
|
contains the contents of the BGP-4 AS_PATH Path Attribute.
|
|
This object may be parsed using the rules defined for
|
|
Four-octet ASes as defined in RFC 4893. RFC 4271, Section
|
|
4.3, 'Path Attributes: b) AS_PATH' as amended by RFC 5065,
|
|
Section 3 defines the general format of the AS_PATH path
|
|
attribute and its code points.
|
|
|
|
In brief, the AS_PATH is composed of a sequence of AS
|
|
Segments. Each AS Segment is represented by a triple:
|
|
<path segment type, path segment length,
|
|
path segment value>.
|
|
|
|
The path segment type and path segment length fields are
|
|
one octet in length each.
|
|
|
|
The path segment type field may be one of:
|
|
1 - AS_SET (RFC 4721, Section 4.3)
|
|
2 - AS_SEQUENCE (RFC 4721, Section 4.3)
|
|
3 - AS_CONFED_SEQUENCE (RFC 3065, Section 5)
|
|
4 - AS_CONFED_SET (RFC 3065, Section 5)
|
|
|
|
The path segment length field contains the number of ASes
|
|
(not the number of octets) in the path segment value field.
|
|
|
|
The path segment value field contains one or more AS
|
|
numbers, each encoded as a 4-octet length field in network
|
|
byte order.
|
|
|
|
Note that since an SNMP agent may truncate this object to
|
|
less than its maximum theoretical length of 4072 octets
|
|
users of this object should be prepared to deal with a
|
|
truncated and thus malformed AS_PATH. It is RECOMMENDED
|
|
that when such truncation would occur on the boundary of an
|
|
encoded AS that the partial AS be discarded from this
|
|
object and the object's size be adjusted accordingly.
|
|
Further, it is also RECOMMENDED that when such truncation,
|
|
either alone or in conjuction with the truncation of a
|
|
partially encoded AS described previously, would yield an
|
|
empty path segment value field that the path segment type
|
|
and path segment length components of the truncated AS_PATH
|
|
also be discarded and the object's size be adjusted
|
|
accordingly."
