[j-nsp] Unfamiliar with Juniper M10 Config Files

[Loopback EZ]

I am replacing an old Cisco router with a Brocade MLX as IBGP peer to a 
Juniper M10.  I am only getting 250K routes and I have NO filtering 
enabled.  I know that the Juniper is receiving a full EBGP route table 
but is only passing 250K to any of its internal IBGP peers including the 
old Cisco.  Suspect that there is route summarization happening so it 
would not overrun an old Cisco SUP module.  Where should I look for 
summarization or any other possible cause in the Juniper config?
