Honestly, this.  Your only real choice is what of 2 pipes to chuck it out of.

Full tables vs partial and a default don’t make the process much more intelligent for 1 site dual homed, and as 
mentioned routing policy will have more influence.

It’s pretty pointless for a small ISP to get full routes, because the BGP tables are so highly manipulated. It’s 
better to just get “company” routes for each upstream, and then use your own traffic engineering via prepending and 
static or policy routes to balance the outbound traffic the way you like.

Hello all. I am having a hard time trying to articulate why a Dual Home ISP should have full tables. My 
understanding has always been that full tables when dual homed allow much more control. Especially in helping to 
prevent Async routes.


Am I crazy?
