Chapter 4 Operational Concepts and Configuration Examples

For example: To specify next-hops 149.49.54.1 and 149.49.75.1 as a static route to the network 10.1.1.0, perform one of the following:

Use the single ip route 10.1.1.0 24 149.49.54.1 149.49.75.1 command specifying all next-hops together.

Use the individual ip route 10.1.1.0 24 149.49.54.1 and ip route 10.1.1.0 24 149.49.75.1 commands.

Note: Next-hops can only be added to an existing static route if they have the same preference and metric as the currently defined next-hops.

X330WAN supports the following Static Route configurations:

“via interface” Static Route

Permanent Static Route

Discard Route

These configurations are described below.

“via interface” Static Route

PPPand Frame Relay allow for a Layer 3 interface to be established without knowing in advance what the next-hop on the other side of a Serial link is. In this case you can specify a Serial Layer 2 interface as a next-hop instead of providing a specific next-hop IP address. This is equivalent to specifying the node on the other side of the Serial link as the next-hop when its IP address is unknown. The “via interface” option is configured by specifying the type and the number of the Serial interface using the ip route command.

For example: The command ip route 193.168.10.0 24 serial 1:1 creates a static route to the network 193.168.10.0 24 via the Serial 1:1 interface.

A static route can have both “via interface” and IP addressed next-hops, with a maximum of three next-hops. If such a combination is required, separate ip route commands should be used for the “via interface” static route and the IP addressed next-hop routes. Also, if more than one “via interface” next-hops are required, each must be configured by separate ip route commands.

Permanent Static Route

X330WAN enables you to configure a static route as a permanent route. Configuring this option prevents the static route from becoming inactive whenever the underlying Layer 2 interface is down. This prevents routing table updates from being sent each time an interface goes up or down when there is a fluctuating Layer 2 interface on the static route.

Configure the ‘permanent’ option using the ip route command.
