Hi Ryan,

Could it bet hat I need 2x MR2 or perhaps 3x SFM1?

sh module 
==========================================================================
                    *** BigIron RX-4 CHASSIS ***

        Module                             Status      Ports  Starting MAC
M1 (left): RX-BI-MR2 Management Module (High Value)     Active
M2 (right):
F1: RX-BI-SFM1 Switch Fabric Module         OK
F2: RX-BI-SFM1 Switch Fabric Module         OK
F3: RX-BI-SFM1 Switch Fabric Module         not present
S1: RX-BI-4XG 4-port 10GbE Module  CARD_STATE_UP    4   000c.dbf5.1200
S2:
S3: RX-BI-2XG 2-port 10GbE Module  CARD_STATE_UP    2   000c.dbf5.1200
S4: RX-BI-2XG 2-port 10GbE Module  CARD_STATE_UP    2   000c.dbf5.1200
==========================================================================

Thank you for trying to help Ryan, perhaps it is a quick fix after all and I just overlooked the fact I need two MR2's or some other setting.

Hmm. Are you certain you have an M2 management module?

I don't have any RX's here to check against. We have many other flavors of Foundry/Brocade but none with anywhere near 250+ BGP peers.

I would suspect 'session limit' is more for traffic sessions than BGP sessions.

Sorry I couldn't help. I've found over the years that many never think to look or didn't know about 'sh def val' and had no idea that 'max capable' didn't mean 'max configured'. I was hoping it would be a quick fix. :)
