Configuring IP Routing 103

See “Configuring Static Routes” on page 103 to configure routes manually, and “Learning Routes with OSPF” on page 106 to learn routes dynamically.

Assigning Addresses To assign addresses and enable IP routing, follow these steps: and Enabling

IP Routing

1Assign an IP address for each LAN and WAN port or virtual port that will route IP using:

SETDefault !<port> -IP NETaddr = <IP address> [<subnet mask>

[Ones Zeros [MTU]]] UnNumbered

If you are using a BOOTP server to obtain your IP addresses, see “Assigning Addresses Automatically from BOOTP Servers” on page 108.

CAUTION: An IP address assigned to port 0 is considered the IP address for all the interfaces. As a result, the bridge/router behaves as an IP host for Telnet access and network management and stops routing IP packets. Do not configure an IP address for port 0 if you want to route IP packets

2Enable IP routing by entering:

SETDefault -IP CONTrol = ROute

Configuring Static A static route is a user-defined route by which a network can be Routes reached. If you want to eliminate route advertisements required for

dynamic route learning and optimize the use of the available bandwidth on slow serial data links, you must add the route as a static route.

If a destination network is reachable with both a static route and a learned route, the router uses the static route unless you specify the optional Override value in the ADD ROUte command. If a learned route is available, regardless of precedence, it overrides the static route when using the Override value.

You should use static routes only if your network is small and unchanging.

To set a static route, use:

ADD -IP ROUte <IP address> [<mask>] {<gateway> !<port>} <metric>

[Override]
