Dave, I have a dumb question regarding multiple defaults. Lets say that you had a multihomed BGP config connected to 2 different providers. Lets say that you had 2 routers below the firewalls sourcing the default. Then take a look at the routing tables below these 2 routers. Wouldn't nearly every routing proto (other than RIP assuming the hop counts were the same) only list 1 default? Wouldn't it be true that outbound traffic patterns would be based upon metrics from the routers sourcing the default? If this is true, then it's not really load balancing. I can think of scenarios were nearly all outbound traffic would be destined for only 1 of the 2 links. I'm sure I'm missing something dumb, but figured it was worth asking anyway.
