Setting up default-route on both of my border routers addressed the needs.

I feel, asking to recieve (and use) default route appears "cleaner" than
hacking routing protocol ways. Unless, one does as you just did. Right?


Yes, asking ISP to send out default-route via BGP sessions
will be better then manually setup one. A default-route from
dynamic routing protocol can disappear properly in case something
wrong over the link, while manual one could possibly create a
black hole.

BTW, this thread was talking about the use of single-AS in different
sites. I think it is no doubt doable.
