Routing Policy and Manipulation

Question Image

Refer to the exhibit. Which attribute can Router 1 modify so that only its other iBGP peers prefer 192.168.4.2 as the next hop for route 192.168.3.0/24?

  • A MED
  • B local preference
  • C origin
  • D weight
Explanation

Local preference is an intra-autonomous-system BGP attribute exchanged with iBGP peers; BGP prefers the path with the highest local preference. Assigning a higher local preference to the path with next hop 192.168.4.2 causes other iBGP peers to select that path, without advertising the preference to eBGP peers. Weight is local to a single router.
