Brocade MLX Feedback

I've been running NetIron (MLXe + CER-RT) for quite some time, mostly happy
with the products.

Of course, there are always some unforseen / silly / nasty things that
still turn one's mind upside down. What we noticed so far :

    - ISSU / hitless protocols upgrades : we have been pounding them to get
it right, an RFE has been submitted for quite some time now but it's not
there yet,

    - Support of route reflection for VPLS auto discovery : same as above,

    - Adding packet capture (PCAP) capabilities : newly submitted RFE,

    - Adding BGP flowspec support : same as above,

Also, BFD is always a little sensitive when the routers' CPU spike even if
it's supported in hardware.

All in all, and from a price/performance perspective, I would still
recommend them if they match your business case (especially CER-RT for
small colo / IP transit / IXP PEs and/or BGP route reflection).
