Configuring Static Routing TablesIf two subnets are separated by more than one Windows NT machine or bya router, Windows NT can route between the subnets if you manuallyconfigure the routing tables. Static configurable routing issupported, but neither routing information protocol (RIP) or OSPF aresupported.
The ROUTE.EXE command manually configures network routing tables.ROUTE has the following syntax:
route [-fs] [command [destination][gateway]]
-f Clears routing tables -s Packets for which no destinations are found are routed to the smart gateway.
add Adds a route delete Deletes a path print Prints a route change Changes an existing routeAll symbolic names used for gateway and destination are looked up inthe database files NETWORKS and HOSTS.
