I have 1 leased lines that connect 2 offices. At each end, there are 1 modem and 1 1721 router (with a WIC-2T). We use WIC1 for this leased line. The other port (WIC0) is for the next leased line to the other remote office that we will implement next month.
The IP of WIC1 is 172.16.1.94/30 and 172.16.1.93/30 at each end of the line. The IP of the FastEther0 at the local office is 192.168.1.31/24 . FastEther0 is connect to a switch that many other PCs in the LAN connect to.
We need the PCs (in 192.168.1.0/24) be able to commicate with the remote office. And vice versa. From next month, we need the PCs to commincate with the other remote office that I don't know the IP details neither.
Can someone help me with a basic configuration on the 2 1721 routers?
I am familiar with Unix/Linux/BSD routing. It's my first time play with Cisco router.
Thanks a lot. ZP
