Can a single NLRI have more than one AS-Segment in an AS-path?
Is AS-segment same as a AS-Number in a AS-path ?

1 Answer 1


AS-PATHs contain one or more segments.

  1. Yes, if the AS=PATH includes both an AS-Sequence and an AS-SET.
  2. Not exactly. The segment includes the type (sequence or set), length, and value (list of ASNs). In other words the segment can include more than one ASN.
