128 Configuring and managing IP interfaces and services
NN47250-500 (320657-F Version 02.01)
This example shows dynamic routes added by WSS Software for two VLAN interfaces, 10.0.1.1/24 on VLAN 1 and
10.0.2.1/24 on VLAN 2.
10.0.2.1/24 on VLAN 2.
This example also shows two static routes, which have a next-hop type (NH-Type) value of Router. Static routes have a
default router, listed in the Gateway field. The 0.0.0.0 destination represents a default route. Here, default router
10.0.1.17 is reachable through the subnet on VLAN 1. Route 10.0.1.1/24 resolves the static route that uses the default
router. Default router 10.0.2.17 is reachable through the subnet on VLAN 2 and route 10.0.2.1/24 resolves the static
route to that gateway.

10.0.1.17 is reachable through the subnet on VLAN 1. Route 10.0.1.1/24 resolves the static route that uses the default
router. Default router 10.0.2.17 is reachable through the subnet on VLAN 2 and route 10.0.2.1/24 resolves the static
route to that gateway.
WSS Software adds routes with next-hop types Direct and Local when you add an IP interface to a VLAN, when the
VLAN is up. Direct routes are for the locally attached subnets that the switch’s IP addresses are in. Local routes are for
destination interfaces configured on the WSS itself.
VLAN is up. Direct routes are for the locally attached subnets that the switch’s IP addresses are in. Local routes are for
destination interfaces configured on the WSS itself.
WSS Software automatically adds the 224.0.0.0 route to support the IGMP snooping feature.
If a VLAN is administratively disabled or all of the links in the VLAN go down or are disabled, WSS Software removes
the VLAN’s routes from the route table. If the direct route required by a static route goes down, WSS Software changes
the static route state to Down. If the route table contains other static routes to the same destination, WSS Software selects
the resolved route that has the lowest cost. In the following example, the default route to 10.0.1.17 is down, so WSS
Software selects the default route to 10.0.2.17.

Adding a static route
To add a static route, use the following command:
set ip route {default | ip-addr mask | ip-addr/mask-length} default-router metric
