I will look at that thank Jerry , it is receiving 10 from AS 54 peer ,
just at R6 is , I was just curious to see IE official bgp table outputs
from what the solution , depicts , rack is currently configured
identical to IE's solution , and as far as I can see all is equal , R3
and R6 should be passing on 10 routes each to there common Route
Reflector R5...

Long,
Do a show ip bgp on R3. How many routes is R3 receiving from his EBGP
peer? Next how many of these routes is R3 actually selecting as it's
best path (*>)? R3 will only advertise the routes that R3 would
actually use, not every route that he receives.
