We have two offices. My office has two T1 connections to the Internet. I've ordered Point-to-Point T1 (just the T1 port without Internet connection) to connect our other office to us and to the Internet.
I would like to subnet our class C IP like below:
198.78.142.1 255.255.255.128 (our office)
198.78.142.252 255.255.255.252 (For serial ports that are connecting our two offices)
198.78.142.128 255.255.255.192 (our other office)
I'm having a problem figuring out the "ip route" statements to accomplish the above:
IP route statement for my router here:
ip route 0.0.0.0 0.0.0.0 4.0.240.121
ip route 0.0.0.0 0.0.0.0 38.99.199.153
ip route 198.78.142.128 255.255.255.192 198.78.142.254
IP route statement for our other office:
ip route 0.0.0.0 0.0.0.0 192 198.78.142.253
Are the above ip route statements correct?
Are the Serial configuration for connecting our two offices correct?
