Hi Richard,
Some good CCO links have already been posted. I just wanted to add a quick
point.
This command is useful as a tool for providing a semi dynamic default
route. For example, if you are connected to two upstream networks which
both offer you routes toward a destination, say 10/8 for example, you can
use this command to ensure that your routers chose a default route toward
the most functional of the two. For example, with normal static routes, the
route remains active so long as the immediate connectivity toward the next
hop is alive and well. Hence, should the next hop router have a failure on
one of its' upstream links, or should any other upstream routers beyond it
fail, you routers will still consider the route active and thus send traffic
toward a likely black hole. By using ip default network pointed towards
10/8, which you know is an upstream network, you can protect yourself
against any failures that deter you from reaching that network since those
failures will cause the faulty network to cease advertising 10/8 to you. In
my example, if the active next-hop for 10/8 becomes unable to deliver
traffic there, your routers will dynamic change default toward your
alternate path.
Hope that helps some :)
Pete
