Let me add that the lab I'm doing right now. Asks for you to advertise the
lo0 interface for all devices in the ospf domain. I should not use ip ospf
network command and they should appear with their "proper" netmask. Thats
all that was asked for yet the SG has the BB subnets being allowed in the
through the route-map. I find this annoying as hell, because I don't know
if my logic is faulty or I missed something when I read through the lab. I
see nothing in the BGP section that suggests that i need to do this, because
I can next-hop-self at the borders
