  The route shown in the exhibit is being advertised to the EBGP peer and displays a next hop of itself. However, you do not have a next-hop self policy configured. What would cause this behavior?

  A. The IBGP peers have a next-hop self policy, which the router is exporting to the EBGP neighbors.

  B. The set protocols bgp path-selection as-path-ignore is not set and must be added so the next-hop attribute will propagate from the peer.

  C. The set protocols bgp accept-remote-next hop is not set and must be added so the next- hop attribute will propagate from the peer.
