will ISP peer with 2 local WAN routers?

[maillist at webjogger.net (Adam Greene)]

Thanks, Justin. Yes, we considered that option, too. But then if one WAN
router goes down, the customer will only have connectivity through a single
upstream provider. We'd prefer to maintain connectivity to both even if a
router fails. Switches in front of the routers is no problem.

The gotcha with that is then you need a switch in front of the routers. I'd
just setup a carrier on each router and run ibgp between.
