[j-nsp] ACX Questions

Fri Apr 16 16:03:11 EDT 2021

I run martini rfc 4447 ldp-based l2circuits as well as vpls on our mx204’s and also acx5048’s (I think junos 15.x and 17.x on 5048 and I think it’s 18.x on 204)…  I don’t think I’ve tried mpls on qfx5120 (not sure what version of gfx5100) you use.

I just tried to lab up l2circuit on one of my qrx5120’s and I get a license error for mpls feature

I just received an off list email stating that the ACX5048 does support l2circuit (LDP signaled). Is this the same feature as Ethernet-over-MPLS (L2 circuit)? If so why is it showing this feature is not supported on ACX (or MX for that matter)? Is the feature explorer incorrect? https://apps.juniper.net/feature-explorer/feature-info.html?fKey=6620 <https://apps.juniper.net/feature-explorer/feature-info.html?fKey=6620&fn=Ethernet-over-MPLS%20(L2%20circuit)> &fn=Ethernet-over-MPLS%20(L2%20circuit) 

I do see 

20.3R1

Starting in Junos OS Release 20.3R1, support for Layer 2 circuit to provide Layer 2 VPN and VPWS with LDP signaling.

Thanks all for this information. Aaron I had my client run this same command on their QFX5100, and it too has max 3 labels. It seems the issue is that the client needs a layer 2 transport over a layer 3 network. VPLS is the logical choice, and the ACX5048 supports this according to the Juniper Feature Explorer. The QFX5100, however, does not. What layer 2 over Layer 3 option do you recommend for the QFX5100 to talk to an ACX5048 or MX204 on the other end?
It looks like the QFX5100 supports Ethernet-over-MPLS (L2 circuit). Is this an alternative to VPLS? ACX and MX does not support Ethernet-over-MPLS (L2 circuit) however. It seems there is no common protocol that both the QFX and ACX/MX share in common under the Virtual Private Networks (VPNs) section of the feature explorer. Is there any solution other than replacing the QFX with ACX's or MX's?
