Nortel Networks 2300 Series manual Output for show ip route

164IP Services Commands

Usage When you add an IP interface to a VLAN that is up, WSS Software adds direct and local routes for the interface to the route table. If the VLAN is down, WSS Software does not add the routes. If you add an interface to a VLAN but the routes for that interface do not appear in the route table, use the show vlan config command to check the VLAN state.

If you add a static route and the route’s state is shown as Down, use the show interface command to verify that the WSS has an IP interface in the default router’s (gateway’s) subnet. WSS Software cannot resolve a static route unless one of the switch’s VLANs has an interface in the default router’s subnet. If the switch has such an interface but the static route is still down, use the show vlan config command to check the state of the VLAN’s ports.

Examples The following command shows all routes in a WSS’s IP route table:

WSS# show ip route
Router table for IPv4	VLAN:Interface
Destination/Mask Proto Metric NH-Type Gateway

Table 25 describes the fields in this display.

	Table 9: Output for show ip route
Field	Description
Destination/Mask	IP address and subnet mask of the route destination.
	The 244.0.0.0 route is automatically added by WSS Software and
	supports the IGMP snooping feature.
Proto	Protocol that added the route to the IP route table. The protocol
	can be one of the following:
	• IP—WSS Software added the route.
	• Static—An administrator added the route.
Metric	Cost for using the route.
NH-Type	Next-hop type:
	• Local—Route is for a local interface. WSS
	Software adds the route when you configure an IP
	address on the WSS.
	• Direct—Route is for a locally attached subnet.
	WSS Software adds the route when you add an
	interface in the same subnet to the WSS.
	• Router—Route is for a remote destination. A
	WSS forwards traffic for the destination to the
	default router (gateway).
