[f-nsp] Brocade XMR / Juniper iBGP Interoperability

[James Cornman]

Do you have -X model 10Gbps cards?

BR-MLX-10Gx4-X 4-port 10GbE Module

What about management modules? Do you have other full-route BGP sessions on
that 10Gbps card, and just the Juniper ones are having issues? With a -X
module as listed above, and ipv4-ipv6-2 CAM partition, you should see
something like this:

SSH at router#show cam-partition slot 2

CAM partitioning profile: ipv4-ipv6-2

Slot 2 XPP20SP 0:
# of CAM device                = 4
Total CAM Size                 = 917504 entries (63Mbits)

IP: Raw Size 786432, User Size 786432(0 reserved)


Does it show that?
