For example, in
another, non-dedicated, path that passes through Domain 2. If failover is enabled, all traffic will use
the dedicated path, because the non-dedicated path is not the shortest path. If failover is disabled,
non-TI zone traffic is blocked because the non-dedicated path is not the shortest path.

shortest path. In this situation, if failover is enabled, the TI zone traffic uses the shortest path, even
though the E_Ports are not in the TI zone. If failover is disabled, the TI zone traffic stops until the
dedicated path is configured to be the shortest path.

If failover is disabled, non-TI zone traffic is blocked because it cannot use the dedicated ISL,
which is the lowest cost path.
