Re: Switch/Router

Juniper MX150, except only single PS. But they are cheap enough you could buy two. Upside: most of the MX feature set is available because it is vMX (software) inside. QFX5110 is more expensive but has more ports and dual PS. Downside: Broadcom chipset limitations. On Tue, Dec 12, 2017 at 0
