Hmm - It cant be - Its not just to one nexthop that all the traffic is heading....i.e there are 3 or 4 destination routers (2 ASR1001s, and the ME3600 (2 of those)...so 4 next-hop addresses....we cant be that unlucky that every one of those addresses is being mapped to gi0/0/20...no, just checked, and it arbitrarily changes based on src ip....but, that could be just cef miss-reporting. ....very frustrating.

Thanks Aaron....thats what Im going to try shortly.....Very strange how cef exact route reports it as load sharing, but it obviously isnt.....and the next-hop link you provided, I have to read, but I think that is what is happening...

In my mpls cloud I usually would lag dual gige's together to feed my PE
boxes with more bandwidth.  Worked well for me
