Routing metrics

Hi there. Does anyone know if a value of '1' for the metric on static
routes has a special meaning? I've configured two machines (R-2 and
R-3) running win server 2003 with routing and ras enabled. They are
both connected to a third router (R-3) which has two static routes for
the 'network b' through them. Something like this:

[R-3]
-----------|----------- 'network a'
| |
[R-2] [R-3]
| |
----------------------- 'network b'
| |
[Client] [Client]

If I set, for example, a value of '1' in the metric for the route
through R-2 and '2' for the route through R-3, and I shutdown R-2, a
ping running on the clients stops responding. And yes, both clients
have R-2 AND R-3 as default gateways, so the ping should recover and
start going through R-3. If I use '10' and '20' as metrics instead, it
works as expected.

I know this configuration is quite quirky, but it's just a test, I just
wanted to know if a metric of '1' has a special meaning.

Thanks in advance and sorry for my english.

basically, lower # is the primary gateway or you are using. For example, if R-1 is metric 1 and R-2 is 2, you are using R-1.

Now, if you have two gateways setup on one computer and the computer always uses R-1 even it is don't work because the computer doesn't know that.

Don't worry about the metrics, leave them at "1". what you are doing
(trying to do) is called Dead Gateway Detection.
