[j-nsp] Juniper ACX

[Aaron]

I had a couple different flavors of Cisco ASR920 in my lab recently but
dropped it from consideration since it top'ed out at (6) 10 gig interfaces.
I opted for the Juniper ACX5048 since it's got (48) 10 gig and (6) 40 gig -
so a possible total of (72) 10 gig interfaces.

I tested L3VPN on ACX5048 and it looked good.

I tested L2VPN VPLS BGP Auto Discovered w/BGP Sig and /LDP Sig and both were
functional.

As I've mentioned before on this list, we dropped it due to lack of NG-MVPN
support (limitation in the Broadcom chip used on the platform).

Juniper have no plans to get a custom, cheap chip in there.

So we went with Cisco's ASR920. Does everything we want for half the price
of their ME3600X platform, and works just like a regular ASR1000 router.

When Juniper wise-up, we shall revisit; but not until then.

Mark.
