Router Deployment

Question Image

Refer to the exhibit. An MPLS connection on R2 must be extended to R1. Users behind R1 require dual connectivity for data traffic. Which configuration provides R1 with control connectivity across the MPLS connection?

Explanation

A TLOC extension is configured on the device that owns the WAN transport, binding the inter-router interface to that transport. R2 therefore extends its MPLS transport on ge0/0 through the link to R1. R1 configures that link as an MPLS-colored tunnel interface; control connections are enabled by default on a tunnel interface. The addresses 34.34.34.1/30 and 34.34.34.2/30 also form the required shared point-to-point subnet.
