KJ,
I work for a major ISP and the way you stated by splitting the ip block
into 2 halves, advertising 1 half on 1 router and the other half on the
second router but still advertising the full block on both routers, is the
way we do here. Is the customer's connections from their 2 routers
connected to 1 router or 2 routers of the ISP? If he is connected to 1
router you could do some load balancing with an interface command of 'ip
load-sharing per-packet' on both interfaces of the ISP's access router, if
he is connected to 2 different router, the only way is to split the block.
