[f-nsp] Brocade XMR / Juniper iBGP Interoperability

[Daniel Stephens]

Hi everyone,

I am having a strange issue with our Brocade XMRs when I attempt to exchange routes between a new set of Juniper MX iBGP peers and was looking to see if anyone had any recommendations.

The Brocade XMRs have two line cards, a 20-port 1G and a 4-port 10G card installed, and are running 5.6.0d firmware.

We are integrating two existing networks as a consolidation, with the one network running Brocade XMR and the other running Juniper MX routers. The issue surfaced on the XMRs when we removed route filters on the iBGP sessions between the XMR and MX routers. When lifting the filters and sending routes from the XMR towards the MX, everything is functioning as normal and the MX correctly learn the routes. Our issue becomes when we lift the filter and send routes from the MX towards the XMR. The XMR begins to load the routes correctly, and at some point during this process, the XMR stops forwarding traffic on the 4-port 10G line card entirely (the card to which the MX routers interconnect), and all BGP sessions associated with that line card flap, and OSPF adjacencies drop and re-establish.

I am using the ipv4-ipv6-2 CAM partition profile on the XMR devices. Total number of routes attempting to be passed is a full table of roughly 610K routes.

Even when I remove an XMR unit from service and attempt to load routes from the MX into the XMR, the same anomaly occurs.

Any assistance would be greatly appreciated.

Thanks,
Daniel
