I've been given a task to design a network that's basically should have access to the Internet "whatever happens". The end user's into eCommerce/Trading and they're willing to spend for this.
I have some ideas on my head, the most promising being I use two routers connecting to four ISPs (2 on each router). This router runs BGP and receives partial or full routes (depending on the chosen router model).
Then on the back, I'm thinking of GLBP for single GW setup and load balancing. I may get away with just using the routers as a simple firewall (Adv. IP Services IOS) if an ASA 5500 poses a problem for GLBP's multiple virtual macs.
Further behind, a Cisco Catalyst 4507R with redundant PS and Sup engine to tie them all together.
Can anyone validate this setup? I've read somewhere that GLBP is unable to track BGP routes. Is this true? Any gotchas on this setup?
Thanks!
