SR Linux Configuration and Routing

Which of these statements about the AS path attribute is FALSE?

  • A It is a parameter associated with each prefix advertised to BGP peers.
  • B It is used for route selection.
  • C It is used to uniquely identify a BGP router.
  • D It is used for loop detection.
Explanation

The AS_PATH attribute records the autonomous systems a route advertisement has traversed. BGP uses it for loop detection and as a route-selection attribute. A BGP router is uniquely identified by its BGP identifier (router ID), not by the AS_PATH attribute.
