Routing for media conversion

In theory when using a router it is stated that you must have seperate networks on each side. Now I have a question. I need to get between two sites using a dedicated T1 which means I need to use a router only for media conversion from ethernet to serial back to ethernet. Do I have to use seperate networks or can I do the following? Site A ethernet 192.168.1.X site A serial 192.168.2.X Site B serial 192.168.2.X Site B ehternet 192.168.1.X.

You can use transparant bridging to achieve this. See Cisco.com for configuration examples http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/12cgcr/ibm_c/bcprt1/bctb.htm

Re: Routing for media conversion

So is my above example wrong? Because it seems to be working OK.

Re: Routing for media conversion

192.168.1.0 is connected to your router at site A. To reach the discontigious host on remote site B you have to cross the serial link that connects site B.

How does router A knows to reach hosts on site B when network 192.168.1.0 is local to the router?
