Cisco has VSS (on 6500 class) and H3C has IRF; allowing you to virtualize 2 or more physical switches/routers in an active/active configuration

Juniper also has Virtual Chassis support on the EX-series. The MX also supports active/active multi chassis-LAG. It works as you would expect,


I seem to recall that both of these implementations suffer from some significant limitations around how/what you can do with them, as well as HA options...though that's all I can remember from digging into it (enough to realize it wouldn't work for us) last year.

OTOH, Raptor's "virtual chassis" magic (while it has its own issues...) didn't have these problems. :)
