[j-nsp] Moving onto EX2300

Ups, this was supposed to be on-list.

<plunin at gmail.com>:

Well in fact it's not really about "removing a feature".

Both ex2200 and ex3300 were based on marvell pfe (and control plane cpu as
well) while 2300/3400 have broadcom chips inside. If juniper could, they
would be happy to reuse the same code. But no.

And trust me, you don't want them to even try to rewrite all the features
for the new platform at once (hello those who remember the famous ScreenOS
to SRX and E series to MX BNG "rapid" migration stories).

Not sure, this "hardware limitation" is really that hardware that they
won't ever implement it. VRs were added relatively recently to ex2200/3300,
while it had been known as "hardware limitation" for many years.

Anyway, I won't rely on VRs on this kind of switch both because it implies
a clumsy design, and because it is a rarely used feature, poorly tested and
generating little market pressure in case of bugs.

I am not even sure it's really 100% supported on EX2200/3300, I've recently
seen that cross-VR routes just don't work on ex3300, and it seems to be
rather a feature than a bug.
