I have a silly question. I'm planning on taking an SFP handoff from my carrier and plugging it directly into a Catalyst L2 switch. Now, in the past they have given me circuits with an IP address of 126.96.36.199/30 and had a block of IP addresses "riding" on that circuit. For instance, they would give me a block like 188.8.131.52/28. So, normally I'd plug that directly into a router and do NAT to expose my internal webservers and whatnot. Now I have a scenario where I want to use external addresses for a few servers. My thinking was to plug the servers into several ports along with the SFP handoff from my carrier and put all those ports in the same VLAN. But I was thinking no one could access the 184.108.40.206/28 network if I gave the vlan interface the IP address of 220.127.116.11/30. Is this true? So, what I wanted to do was just give the VLAN interface an IP address of something inside that network such as 18.104.22.168/28. But then it seems the IP addresses would be lost because they couldn't get to 22.214.171.124/30. What can I do in this situation besides add a router to the mix? TIA.
You are correct in reference to the L2 switch only having one vlan interface, typically used as a management SVI. From your post you need something that can provide routing. You can still use a switch, it will just need to be a L3 switch.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
