In the MPLS network below, assume that least-cost paths are used by the MPLS network, wherever possible. A 1 3 B E 10 3 F (a) If 1+1 end-to-end protection is required for a connection between A and F, and a connection between A and D, determine primary and secondary least-cost paths in each case. (b) Assume that local protection of some form is provided instead. Consider two LSPs, one from A to F and another from A to D. These least-cost paths share a single link - link BE.
