[j-nsp] Cost of vMX

[Aaron Gould]

But I guess in a situation where you already have a data center or virtual environment like what is being talked about, and you simply add in vMX for vRR or vCGNat, then perhaps that makes it more bearable 

Btw, can you actually emulate the MS-MIC-16G/MS-MPC-128G hardware cgnat functions on vMX ?!

This...

Looking at virtual routers - even from other vendors - what quickly
stands out for me is that if your traffic volumes are typically low, but
you get value in things such as being able to host a ton of customers on
the same chassis/VM, hold millions of routes for several years without
worrying about hardware resources (in the case of RR's), need to crunch
numbers very quickly in CPU (in the case of a virtualized Netflow
collector such as Arbor), then it makes very good sense.

If you're trying to forward 10's of Gbps through a virtual router on
general-purpose x86 hardware at any meaningful scale, you're quickly
going to see all your money go into:

    - The server hardware
    - The hypervisor license
    - The VM license

Doesn't make for a good prospect, if I'm honest, with today's
state-of-the-art.

While you could build a virtual router capable of forwarding 100Gbps
aggregate, it's going to be cheaper for you to work with a purpose-built
router/switch.

Mark.
