Configuring the Track's Action—Associating the Track
with a Route
When you use network monitoring to control routes, you must associate a
track with a route.
You can associate a track with:
a static route
a default route received from a DHCP server
a default route received with a negotiated address

Associating a Track with a Static Route

When you associate a static route with a track, the route's presence in the
routing table depends on the track's state (which, in turn, depends on probe
tests). If the track's state is Pass, the route remains in the table and is used to
forward traffic. If the track's state becomes Fail, the track removes the route
from the table. And, when the track's status changes back to Pass, the route
is reinstated.
A track can reinstate a route that once again becomes valid. Remember to
configure a route map to forward the probe traffic out the primary interface
so that the probe is reinstated only when the primary route becomes valid.
Monitoring and controlling the route serves these functions:
If your router knows an alternate route for the traffic, it can begin using
that route instead of the failed one. (This alternate route might be a
floating static route or a load sharing route.)
Sometimes, of course, the alternate route is no longer valid, either, partic-
ularly if the loss of connectivity arises from a failed network connection
close to the ultimate destination. You can configure one track to monitor
one route and one track to monitor the other route so that no matter what
the problem is, the routing table remains accurate.
