My small company needs to scale up, and with that, our SLA is also going up. I'm in a bit over my head on building a fully redundant network. (there must be no single point of failure). Load balancing is not a major concern as we do not have that much traffic. This is all about trying to acheive 99.999% or 99.9999% up time.
We have to connections to the world coming in. One from a Teir1 provider and another form a Tier2.
We have a dozen hosts behind this network, each host has dual nic.
We will be setting up a mirror location, geographically far apart, within six months.
I imagine that I will need two Border Gateway Protocol boxes, one for each of our connections? Beyond that, I really don't have much of an idea. Any guidance in the right direct will be greatly appreciated.
