Refer to the exhibit. vEdge102 must establish a control connection across MPLS by using TLOC extension and dynamic routing. Which configuration accomplishes this task?

Explanation

A Layer 3 TLOC extension requires dynamic routing between the WAN edge devices. vEdge102 must form BGP with vEdge101 at 172.1.1.2 and make its 172.1.1.1/30 link a tunnel interface using the restricted MPLS color. This provides reachability through vEdge101’s MPLS transport for vEdge102’s MPLS control connection. Cisco documents that Layer 3 TLOC extension requires a routing protocol between the SD-WAN devices and uses a tunnel interface for the extended TLOC.
