Hi everyone, let me apologize up front for my absolute lack of knowledge. I'm new to routing and cisco in general. I'm inheriting a rather simple setup but would like to approach the next steps with a good strategy. Currently we have a 2901 router with public IP's on bother interfaces. The internal facing interface is our gateway for some webservers and a firewall. Not we are looking to add a colocation site and establish a site to site VPN using another 2901. My goal is to have the colocation use the same internal 10.100.0.0/23 network. My question is what is the best way of going about this since the router at the main site has public IP's on both interfaces? Do I need to multi-home the internal facing interface? If so, what else needs to be done?
Thanks in advance.
Rob
