/* There is an edge case, when number of links in a Router-LSA may be 0 without
breaking the specification. A router, which has no other links to backbone
area besides one virtual link, will not put any VL descriptor blocks into
the Router-LSA generated for area 0 until a full adjacency over the VL is
reached (RFC2328 12.4.1.3). In this case the Router-LSA initially received
by the other end of the VL will have 0 link descriptor blocks, but soon will
be replaced with the next revision having 1 descriptor block. */
