I read something here this week that caught my eye. Arista offers competitive layer3 switches with a very close cisco CLI. They also apparently all run the same binary image and software set. That is quite appealing to me.
But how complete is the image on different hardware? Routers are not switches, switches are not firewalls. Would a switch be able to nat? Is there a rudimentary protection from hostile networks (internet) that can be used? Something like CBAC or ZBFW approach?
Are we finally at the place where we can reduce the stack down to a single switch for small branch offices?
