To change the relative route priority, use the following command:

ospf-as-external | ospf-extern1 | ospf-extern2] <priority>

Configuring IP Unicast Routing

This section describes the commands associated with configuring IP unicast routing on the switch. To

configure routing, follow these steps:

1 Create and configure two or more VLANs.

2 Assign each VLAN that will be using routing an IP address using the following command:

configure vlan <vlan name> ipaddress <ipaddress> {<netmask> | <mask length>}

Ensure that each VLAN has a unique IP address.

3 Configure a default route using the following command:

configure iproute add default <gateway> {<metric>}

Default routes are used when the router has no other dynamic or static route to the requested

destination.

4 Turn on IP routing for one or all VLANs using the following command:

enable ipforwarding {[broadcast | ignore-broadcast]}{vlan <vlan name>}

5 Turn on RIP or OSPF using one of the following commands:

enable ripp

enable ospff

For more information on configuring RIPP and OSPF, see “Interior Gateway Protocols” on page 227.
