Hi, I'm setting up CS 4.1.1 in a datacenter and have been assigned a single /27 block of public IPs. I'm trying to determine the best way to configure the networking, routing and switching for the TOR. On XenServer hosts, I plan to share Public and Guest traffic on one interface with separate management, primary and secondary storage interfaces. So I calculate I need to configure VLANs for Guest and Public similarly to this image: http://www.shapeblue.com/wp-content/uploads/2013/01/PhysicalNetworkingBlog_logicandphysnet-300x226.png I have the traditional (multi-port) router and (L3 Cisco) switch at the TOR with the CS physical networks connected to the switch. How should I configure the switching (VLANs), routing and public IP address assignments? Should I assign all public IPs to the upstream port on the router and forward them in? Should I get another /30 from the DC and route the /27 in? I plan to bring additional guest networks into the router via VPNs and P-t-P circuits later. For now, I only have one guest network coming in on a separate router port. I don't have much practical experience with VLANs in Cisco switches. Thanks in advance, Gene
