We recently initiated a branch office setup in the same city. (Setup is still in process) Currently in Main branch we are using Cisco 2800 series router and Cisco 6500 series Core Switches. Similarly in Branch Office, we have one Cisco 2800 series router and some POE switches.
In order to connect both branches together, we will be acquiring IP/VPN Connection from service provider. The idea is to utilize each others resources.
We are planning to treat our Branch office network as a subnet of Main Branch. Therefore we'll be using the same IP schema but of course on different VLAN. (OR should i treat it as a separate network?)
To my understanding IP/VPN link will terminate on the Router of Branch office and other end will be terminate on the router of Main Office. (Please correct me if i am wrong).
Secondly, do I have to do something else on Router or on Switch to make it work properly? Am I missing anything?
