Routing within a computer

[Chris]

Each computer has two NICs. Each NIC is on a different
subnet and connected to a different switch. The client
computer has a telnet connection to a server on another
subnet.

Can we configure the local client computer to "ROUTE"
traffic from one NIC to another in the event that one NIC
goes down? Both NICs can communicate with the server.

For example, NIC1 is 192.168.10.10
NIC2 is 172.16.22.15
The client connects to the server at 10.33.2.140 using
Telnet through NIC1.
Then, NIC1 looses connection, can the client computer
start using NIC2 SEAMLESSLY to communicate to the server,
without loosing the telnet session?

It will not be seemless. TCP/IP will have to detect that the session went down. At that time it will fail over to the second gateway.
This typically results in the initial session being lost before the second session is initiated. The app itself could be written with
this in mind but telnet does not have this capability. It will loose it's session and terminal. Once this happens though, if you
reconnect, it should reconnect the session.

Thank you,
