I am trying to add redundancy to our network. Currently, we have one ISP connected to one router(2811) wich is in turn, connected to our firewall. I am currently setting up a second ISP going to a second router(2811). I will be running BGP on the routers. What is the best way to connect the routers and the firewall together so as to provide redundency. For now we will only have one firewall but we will be putting in place a backup firewall in about 6 months.
You can configure your 2 router's ethernet interface with HSRP config as when you implement HSRP you will get a virtual single virtual ip address and you can keep your one router lan interface as active and second router ethernet interface as standby.
Configure a single static route on your PIX firewall pointing towards that virtual ip address and all will be good to go.
You can implememt HSRP on lan interface of your router when you implement hsrp you will configure a virtual ip address which you can use to have a static route on your firewall to reach the router lan interface.
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
