address and activate the route. You can create a default route by modifying the
default
profile, or by creating one or more
ip-route
profiles that specify a zero
destination and a valid gateway address.
Figure 4-4 shows a router that resides on the same subnet as the IP2000 Gigabit
Ethernet IP interface. In this example, the system offloads part of its routing overhead
by using a default route to the LAN router.
Figure 4-4. Default route to a local IP router
The following commands define a default route to the local router:
admin> read ip-route default
admin> set gateway-address = 1.1.1.200
admin> write -f
Creating a static route to a subnet
When RIP is turned off on an IP interface, the router cannot reach subnets beyond
other routers on that interface unless it has a static route to the subnet. To enable
access to subnets beyond the local segment, you must configure a static route.
Figure 4-5 shows an example.
Figure 4-5. Static route to a subnet
The following commands configure a static route to the remote subnet:
admin> new ip-route subnet
admin> set dest-address = 135.1.2.3
admin> set gateway-address = 1.1.1.10
admin> write -f
Configuring IP
connection
interfaces for CPE devices
The system creates a routing interface for local
connection
profiles when it starts up.
For interfaces that use pool addresses or are defined in RADIUS user profiles, the
system creates a routing interface when a session becomes active.
