Sending all Traffic to a Network over the Tunnel

You can add a static route to the destination network through the tunnel. From
the global configuration mode context, enter:
Syntax: ip route <destination A.B.C.D> <subnet mask | /prefix length> tunnel <inter-
face number> [<administrative distance>]
Specifying the administrative distance is optional.
Remember that the route to the actual tunnel destination cannot be through
the tunnel. For example, to configure static routing for the tunnel for the
network shown in Figure 9-3, you would enter these commands:
ProCurve(config)# ip route 192.168.2.0 /24 tunnel 1
ProCurve(config)# ip route 2.2.2.0 /24 ppp 1
