Help urgently needed with the design of a new network! History - Previously we have had a single /24 routed to us by a third party isp and just put all the servers in this single subnet.
Obviously this was bad design but I now have the oppurtunity to correct it before moving clients onto the new network so want to get it right!
BGP A/B BGP B/C
Router 1 ------ Router 2
Switch 1 ------ Switch 2
We have a /22 of IP's. The routers are cisco 7204VXR's and the switches are HP procurve 2650.
What I'm after is a design that seperates the clients into their own dedicated vlan's but provides them with a redundant gateway address in case of router failure.
I've experimented with using HSRP to provide the gateway for each subnet but it seems it would use three router addresses per subnet?
Router 1 IP
Router 2 IP
The HP procurve has some basic L3 routing capabilities so it's possible that could be used as the gateway IP for each subnet?
When a customer requests additional IP's beyond their initial subnet - how are they best added - does another gateway IP get assigned etc etc?
