Hi Pshem, The feature designed specifically for what you are looking for is pseudowire headend (or pseudowire headed termination PWHT on junos). I'm just really surprised no one mentioned it already. The limit is 2048 in 15.1 and should be raised to around 15k on 17.1. But as always you should do a fair amount of scaling and performance testing to see if it's suitable for your product scale and BW requirements.
I feel your pain when I was designing Carrier Ethernet solution several years ago when there was no PWHE available had to use two routers at the head-end one to terminate PW into qinq and other with L3 to VRF. The only other option was bridge-domain per PW which obviously does not scale (well not at scales I needed anyways). adam netconsultings.com ::carrier-class solutions for the telecommunications industry:: > -----Original Message----- > From: juniper-nsp [mailto:juniper-nsp-boun...@puck.nether.net] On Behalf > Of Pshem Kowalczyk > Sent: Tuesday, December 19, 2017 10:07 PM > To: juniper-nsp@puck.nether.net > Subject: [j-nsp] Stiching L2 to L3 on MX480 > > Hi, > > We have an existing setup consisting of a number of ACX5k and MX480 > (single MPLS domain).
