A network administrator wants to influence outbound traffic from AS 65001 to prefer a specific exit point. Which BGP attribute should be configured?

  • LOCAL_PREF
  • Weight
  • AS_PATH prepending
  • MED

Explanation: According to the sources, the LOCAL_PREF (Local Preference) attribute is the primary mechanism used to influence outbound traffic decisions within an Autonomous System (AS) . As a discretionary well-known attribute, it is unique because it is carried within an AS only, allowing all BGP routers in that domain to make a consistent routing decision regarding the best exit point . In the BGP path selection hierarchy, the router will always prefer a path with a higher local preference value . While the Weight attribute can also influence path selection, it is local to the router and not propagated to peers, making LOCAL_PREF the standard choice for AS-wide outbound traffic engineering .
