  • A. Configure LDP session protection globally on the device only.
  • B. Configure LDP session protection within the individual VRFs.
  • C. Configure LDP session authentication on the device to enable LDP session protection on each VRF automatically.
  • D. Configure LDP session protection globally on the device and on each neighbor that requires session protection.

  • B. The IGP metric of a tunnel is configured to prefer a certain path.
  • C. A tunnel weight is configured in SPF database the same way as a native link.
  • D. Static route is the only option for directing traffic into a tunnel.
  • E. Forwarding adjacency feature allows a tunnel to be installed in the IGP table as a link.
