If your customer is dual homed BGP makes sense. For a single Internet
connection it does not, simple default route works fine. I have also
used BGP in dual homed scenerios, provider A is a 6M pipe and provider B
a T1. Get partial routing, (connected routes) from B and only learn
default via BGP from A.
The benefits of BGP in a dual homed environment is you take the best
path, you have redundancy and you control the announcement of the
customer networks to the upstreams dynamically.
