Direct Routes; Static Routes - HP 5920 series Configuration Manual

Protocol—Protocol type, which can be DIRECT (direct routes), STATIC (static routes), or FSPF (FSPF
•
routes).
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
•
FCF switch.
FIB table contents
Each entry in the FIB table specifies which physical 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 destination node.
To display FIB table information, use the display fc fib command as follows:
<Sysname> display fc fib vsan 1
FC FIB information in VSAN 1:
Destination count: 2
FIB entry count: 2
Destination/Mask
0xff0101/24
The key items Destination, Mask, and Interface in an FIB table have the same meanings as those in a
routing table.

Direct routes

The sources of direct routes include well-known addresses and the FC addresses that the local switch
assigns to directly-connected N_Ports.
The well-known addresses are usually used to access FCF switches. For usage of common
•
well-known addresses, see
are added to the routing table as the destination addresses of direct routes. In such a direct route,
the destination address is a well-known address, the mask is 0xFFFFFF, and the outgoing interface
is InLoop0.
When an FCF switch assigns FC addresses to the directly connected N_Ports, the FCF switch also
•
adds the direct routes of these addresses to the routing table. In such a direct route, the destination
address is an assigned FC address, the mask is 0xFFFFFF, and the outgoing interface is the VFC
interface connected to the N_Port.

Static routes

Static routes are manually configured by the administrator. After you configure a static route, an FC frame
to the specified destination is forwarded along the path specified by the administrator.
In a simple network, static routes are enough for implementing network connectivity. By properly setting
and using static routes, you can improve network performance and guarantee bandwidth for critical
network applications.
