Hi, Gert:
 
Do you or your company have experiences to provide the inter-AS option B/C services to customers? If so, how do you prevent the overwhelming VPN routes sent to you via ASBR(Option B) or RR(Option C) accidentally ? Just using BGP max-prefix features? Or other mechanism?

Wish to hear your solution.

[WAJ] We are also keep in mind this wary when designing new features for BGP. Would you like to point out clearly if RD-ORF mechanism violates this?
