If your router does not know an alternate route for the traffic, at least the
traffic does not consume any of the relatively limited bandwidth on a WAN
connection.
You associate a route with a track with the same command with which you
create the route. From the global configuration mode context, enter:
Syntax: ip route <destination network A.B.C.D> <subnet mask | /prefix length> <next-
hop A.B.C.D | forwarding interface ID> [<administrative distance>] track <name>
Replace <name> with the track's name. For information about other options,
see the Basic Management and Configuration Guide, Chapter 11: IP Rout-
ing—Configuring Static Routes.
If the particular route has already been entered, you can add the track by
reentering the command and including the track <name> keyword. Make
sure that you match the existing route exactly using the same forwarding
interface or next-hop address. Otherwise, the ProCurve Secure Router OS will
add the monitored route as a new floating static route and not monitor the
existing route.

Associating a Track with a DHCP Default Route

Some service providers require that your ProCurve Secure Router receive a
DHCP configuration on the interface that connects to that provider. These
configurations can include a variety of settings besides an IP address, one of
which is a default route.
See the Basic Management and Configuration Guide, Chapter 13: Dynamic
Host Configuration Protocol (DHCP) for information on the advantages and
disadvantages of accepting a default routes; the instructions in this chapter
assume that you accept the default route.
You can configure the ProCurve Secure Router to add the default route as a
monitored route. The default route now behaves exactly as a monitored static
route, in that it only remains in the routing table when the associated track's
state is Pass.
You should associate the track with the default route at the same time that
you activate the DHCP client on the interface; you perform this task from the
configuration mode context of the interface that receives the DHCP address.
