R1 is exporting 2000:FEFE:100::/64 to R2 over the EBGP peering session as shown in the exhibit.

What will R1 use for this route’s protocol next hop when advertising it to R2?

A.
2000:FEFE:89::1

B.
172.16.1.1

C.
10.1.1.1

D.
::FFFF:172.16.1.1

Explanation:
When a BGP router reports itself as the next hop, whether because of an explicit neighbor next-hop-self
configuration or implicitly as a result of participating in an EBGP session, BGP allocates a new in label and
adds an entry to the MPLS forwarding table, creating a label-to-next-hop mapping.
Note: When a BGP router does not report itself as the next hop, whether because of an explicit neighbor nexthop-unchanged configuration or implicitly as a result of a participating in an IBGP session, BGP does not
allocate a new in label. Instead, if the route is advertised as a labeled route, BGP uses the existing out label.
This feature is used mainly on route reflectors.
