Description

Currently, if the neighbor's cost is equal to zero the routing table calculation fails and no routes are registered to fib. Even though cost zero is not a practical scenario, the link-state routing-table calculation should not fail.

Example:

Triangular topology with the cost from each node to another is equal to zero.

A ----> B, cost 0
A ----> C, cost 0
B ----> C, cost 0
