Rib or Fib for the million - thats the question - but in any event the following will most likely work for you. BTW, full table is now over 600K in size. 1) Choose one Transit and take their full table. (pick whatever reasons cost savings, bigger pipe, coin flip, etc.) 2) With the second transit use a filter to drop all everything /22 or smaller. Now check your tables , see if you have enough room. 3) Next add your peers - no filtering and lpref those routes about the transits. 4) Ask both transits to send you a default route. If this doesn't fit, use some more policy filtering and while this is up and running begin the search for a router with larger tables to replace it...as the tables will soon grow larger. Thank You Bob Evans CTO

The specs say I can get '1 million routes' on it, but as far as I have been advised, a full table of internet routes numbers more than 530k by itself, so taking 2 full tables seems to be out of the question (?).Sounds like you have enough router resources to do your peering and take 2 full feeds.
