FCF switch is 0x010000. A network mask is made up of a certain number of consecutive 1s. It can
be expressed in hexadecimal format or by the number of 1s.
Preference—There might be direct routes, static routes, and FSPF routes to the same destination. All
of these types of routes are assigned preferences. Direct routes have a preference of 0, static routes
have a preference of 10, and FSPF routes have a preference of 20. The optimal route is the one with
the highest priority (smallest preference value).
Cost—Cost of the route. For routes to the same destination and with the same preference, the route
with the lowest cost is the optimal one. The cost of direct routes is 0. The costs of static routes and
FSPF routes are configurable.
Interface—Specifies the interface through which a matching FC frame is to be forwarded out of the
FIB table contents
Each entry in the FIB table specifies which interface a packet destined for a certain destination node or
FCF switch should go out through to reach the next hop (the next FCF switch) or the directly-connected
To display FIB table information, use the display fc fib command as follows:

The sources of direct routes include well-known addresses and the FC addresses that the local switch

The well-known addresses are usually used to access FCF switches. For usage of common
