A company wants to configure BGP on a router so that other BGP neighbors cannot influence the path of a particular route .which action must be taken to accomplish this configuration ?

Question

Options

• AConfigure a low router ID for the route
• BConfigure a high local preference for the route
• CConfigure a high weight for the route
• DConfigure a low MED for the route

• A
  13% (4)
• B
  78% (25)
• C
  6% (2)
• D
  3% (1)

Explanation

Configuring a high Local Preference (B) prevents external BGP neighbors from influencing a route's path selection. Local Preference is an iBGP attribute that is only shared within the local AS - it is never advertised to eBGP peers. By setting a high local preference on a route, the local AS will always prefer that path regardless of MED or AS_PATH values advertised by external neighbors. Weight (C) is also local to the router but is Cisco-proprietary and not propagated even within the AS. Local Preference is the correct choice because it controls outbound path selection across the entire AS while being immune to external neighbor influence.
