Displaying IP Routes To display IP routes, use the following command:
display ip route [ destination ]
The destination parameter specifies a destination IP address.
To display the IP route table, type the following command:
WX1200# display ip route

This example shows dynamic routes added by MSS for two VLAN
interfaces, 10.0.1.1/24 on VLAN 1 and 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.
MSS 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 WX switch itself.
MSS automatically adds the 224.0.0.0 route to support the IGMP
snooping feature.
