I am designing a internet edge firewall network.
Currently the customer has two Core 6500s connected with each other through Fiber Link and these switches are located in two seperate rooms which are 300 m away from each other.
The customer also have two internet connections from different providers, ISP1 is Room# 1 and ISP2 in Room# 2. There is no BGP running.
The customer is desiring to have high availability design where if primary firewall goes down then standby should take over. The same applies to internet connections.
These internet connections are mainly providing access to web servers from outside, S2S and SSL Remote Access VPN
The web servers should be located in DMZ.
My concern is - How do I physically connect each device to provide redundancy ?
