setting up multihomed server to use failover/redundancy

Hi Everyone!

I have a multihomed PDC, which has two NIC connections and connects to two
separate switches. Here is a simple diagram:

[NIC1]------[Switch1]
| \ ::::::::::::::
| \--[T1]-----:: The ::
[PDC]----| :: ::
| /--[DSL]----:: Internet ::
| / ::::::::::::::
[NIC2]------[Switch2]
/
[LAN]--/

NIC1:
ip - 62.83.192.x
gw - 62.83.192.x

NIC2:
ip - 10.0.0.1
ip - 65.201.56.x
gw - 65.201.56.x

The problem: I need all my outbound Internet traffic to be routed out the T1
router. However, It seems instead that everything is being routed through
my secondary DSL connection.

I am fairly new to multihomed connections, so I am not sure where to begin.
Please help!


Kind Regards,

Raven
 
Make a persistant route to your local subnet over the second NIC - use the
"route" command with the "-p" switch ...then use the T1 connection as your
default gateway on both NICs.
 
Jack,

Could you send an example? I am not sure which addresses to use for Network
Destination, Gateway, or Interface.

Thank you SO much for your help!


Regards,

Raven

Would this still allow the DSL connection to be used as a failover if the T1
suddenly dies? Should I leave the DSL gateway with a larger metric?
