I'm wondering how many of you who are multihomed also add default routes pointing to your providers from whom you are receiving full feeds. If so, why? If not, why not?
Back when I worked for the DNC we ran into a problem with the TCAM size. Given the DNC's focus on the U.S., network reliability to the /8's operated out of the APNIC and RIPE regions was much less important to us. So, we filtered BGP announcements from within those /8's and relied on covering routes to get our packets there instead. I used covering /8's instead of a default, but a default would have been as effective.
