Yes riddles indeed, but I can't find a resolution! If there's a simple
answer will you please be kind and just tell me about it? Is it to:
1. use confederations instead of reflectors
2. redistribute bgp into ospf and vice versa
3. either of the above
4. or none of the above?
Thanks for your help :)
Tarek
