It seems in such a case, the traffic still doesn’t know where to go, but you don’t realize it because you have a default. Then you pass the traffic to one of the providers who doesn’t have a route for it and they drop it instead of you. If you see something different, then, by definition, said provider is not feeding you a full set of their tables, or, they, too, are depending on a default and are not receiving a full set of tables.

I have seen cases where if there is no default route, the traffic didn't know where to go, even with full routes from all my providers. -Mike -----Original Message----- From: NANOG [mailto:nanog-bounces () nanog org] On Behalf Of Berry Mobley Sent: Tuesday, November 04, 2014 12:47 PM To: nanog () nanog org Subject: Default routes on BGP routers with full feeds 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? Thanks, Berry
