it seems it gets the bgp route for 147.28.0.0/16 and then can not resolve the next hop. it would not recurse to the default exit. of course it was solved by ip route 147.28.0.0 255.255.0.0 42.666.77.11 but i do not really understand in my heart why i needed to do this.
Neither do I, Randy. I have seen recursive routing done - perhaps on a juniper - i really cannot remember. Given that the packet would be originating from the device itself (not hardware forwarded), it would make sense that it should be able to perform a recursive lookup. I'd put it down to an implementation thing.. Unrelated, I was doing some thinking about a multihomed site and using BGP advertisments sent out one link (provider 1) to influence the sending of the advertisments out of the other link (provider 2). Long story short I needed to know how long bgp nlri's take to traverse the net, and subsequently have a paper that you co-authored open in another tab - well done! :)
