They probably want next hop preserved for this type of device so they can get that from ibgp. Ebgp of course does full tables and communities can be sent no problem.
You got to remember, the smartest engineers don't work at these vendors in the "customer facing role" and they probably have their script they learned in 2 weeks of training - you are messing with them when you ask for deviations of that script!
Don't worry too much about introducing a route reflector client in your network - simply make them use the community "no advertise" upon receipt if possible so they can't do anything with the routes.

Subject: IBGP Vs. EBGP
Dear All,
I Hope if someone can advice me about this Issue,
In our AS there is a New test device thats works as J-Flow (some sort of Netflow caching) is being insterted into out Network,
They Want to Peering with our Internet Gateway Router as IBGP,
however our Rules is to not Config any IBGP peering with a box that is not fully controlled and managed by our side.
We said that we want to config peering as EBGP,however they claim that EBGP peering didn't give them required information as Full internet Routing Table and Full Community Issues and they Want it IBGP.
Anyone can advice me about this Issue,if i can Config It as EBGP but find a way to let Test Box feel like IBGP.
Or Develop a Policy for IBGP Peering,however that will make me to config IGW as Route Reflector and Will Impact Our Process from Changing it as Router Contains only a Default Route to a RR peer IBGP with Test Box.
Thanks,Osama
