Thanks. Someone else also mentioned the need for 2 routers for full
redundancy. What
I'm not understanding is why we need to IP blocks to achieve loadbalancing.
That we'd
need DNS round robin if we're running 2 blocks makes sense, but why the 2
blocks? Also,
are both your lists assuming that the ISPs run BGP with us?
Thanks for the help.
