Hi, we have a internet connection delivered as a 100Mb Ethernet connected directly into our MS ISA FW. Dont know the actual speed but it amazing fast internet connection. Now we want better redundancy and the ISP offer us a secondary 100Mb connection connected to another core router in the ISPs backbone. But they tell us we need to have two routers that support VRRP and asymmetric routing. So i need to buy two routers and put those in front of our FW. Nothing else is required from the routers except deliver this functionality. I do not want to sacrifice speed but i have a limited budget, what Cisco product(s) should be a option for me?
Have you tried looking at these PDF documents yet?
1. Portable Product Sheets - Routing Performance
2. CISCO INTEGRATED SERVICE ROUTERS
There are several design options you could go for here. It doesn't sound as if you have redundant ISA firewalls, so you need to ask do I need redundant routers?
Of course if you're buying redundant circuits then it makes sense to have 2 routers and 2 firewalls so you have full resiliency through the network path.
Anyway Cisco 1805 is a fairly low end router that will route traffic at 100MB. You could impliment one of these and plug both internet lines in the WAN side. On the LAN side plug in your ISA
Or you can buy two Cisco 1805 and use HSRP (better than VRRP) between the two routers. This would give you a more flexable design and enable to add redundany to your ISA in the future.
