There is a T1 already in place at the main office and they are running in the IP range of 172.16.0.0 (the default gateway is 172.16.0.1). They have a Cisco router that they want us to configure with a T1 CSU/DSU to a branch office that is getting a new T1 installed. They are currently using DSL at the branch office and will be getting that disconnected soon. They want the internet from the main office to be used at the branch, which is going to be on the IP 172.17.0.0. Here is what my current intereface looks like for the router at the branch office...
ip address 172.17.0.1 255.255.255.0
ip unnumbered GigabitEthernet0/0
no clock rate 2000000
service-module t1 clock source internal
service-module t1 timeslots 1-24
What else needs to be added so that the branch office knows where to forward it's internet traffic? And will the main office and the branch office be able to share files? Thanks again!
