Suppose that nodes in the network shown in Figure 3.59 participate in link-state routing, and C receives contradictory LSPs: one from A arrives claiming the A–B link is down, but one from B arrives claiming the A–B link is up.

(a) How could this happen?

(b) What should C do? What can C expect? Do not assume that LSPs contain any synchronized timestamp.
