Brook Reams sent me an interesting tidbit: Brocade is the first vendor that actually shipped a VXLAN VTEP controlled by a VMware NSX controller. It’s amazing to see how Brocade leapfrogged everyone else (they also added tons of other new functionality in NOS releases 4.0 and 4.1).
The really interesting part
Every other shipping hardware VXLAN gateway (Arista and F5) that integrates with vSphere environment implements multicast-based VXLAN.
Brocade decided to skip the multicast VXLAN support and implemented only VMware NSX gateway functionality. Obviously they don’t believe in viability of Cisco’s Nexus 1000V (or VMware’s vCNS).
- Arista has a shipping L2 VTEP that uses IP multicast. They might have OVSDB agent (which is needed to work with the NSX controller), but it’s not yet documented in public EOS documentation.
- Nuage VSG 7850 is also shipping, but does not work with either multicast-based VXLAN or NSX controller. It uses MP-BGP to integrate with other controllers within the Nuage's Virtual Services Platform (VSP).
- Cisco is going its own way with ACI.
- Dell seems stuck – the Z9000 documentation published on their web is almost a year old, everything else is older.
- HP claims hardware VXLAN support on FlexFabric 5930AF switches (which probably means “we’re using Trident-2 chipset”); haven’t found anything VXLAN-related in their manuals.
- Juniper is promising VXLAN on QFX5100 and MX-series routers; it looks like they haven’t shipped yet.
