Hi Bardo,
One thing you should be aware of is that the RX are pretty much at the end of
their life, and no longer being sold in Europe. Brocade isn't implementing new
features anymore as far as I know, and one of those missing features is IPv6
VRRP-e support which you'll want to make your server gateways redundant.
In our experience running lots of ARP and mac addresses on the RX will also
melt it down. The MLXe doesn't have this problem.
I would recommend getting MLXe routers for all locations: go with M-blades for
your server PoP (max 256k routes in hardware if you want to use high density
blades) and X-blades for your full table BGP PoPs (max 1M routes in hardware).
Try to use only 8x10G blades or higher density, you'll get some more perks out
of that such as per-VLAN snmp polling and better use of your switching fabrics.
Best regards,
Martijn Schmidt
