[j-nsp] ACX Questions

Fri Apr 16 19:34:54 EDT 2021

Hello everyone.

We have used the QFX5120 with L2circuit for long. Now in version 19.4R3-S2 it is possible to use this this function in aggregate interfaces. Log time effort to get this function back again.  For both 48Y and 32C.

The balancing feature is supported only by DLB for now (not FAT or EL)

You also need to understand the need for policers in tunnels. Types of signaling and tunnel scalability, depending on chipset (T3).

But they work well for some limited projects.

The suggestion is to ask your SE for a POC and approve everything you need, in addition to testing scalability.

See the new ACX7100-48L and ACX7100-32C housings that are coming out with J2. They look interesting and promising (features and scalability)

We should test them soon.

Att,

Giuliano

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://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fapps.juniper.net%2Ffeature-explorer%2Ffeature-info.html%3FfKey%3D6620&data=04%7C01%7Cgiuliano%40wztech.com.br%7Ca894125d52644bd4059a08d901135ff1%7C584787b077bd4312bf8815412b8ae504%7C1%7C0%7C637542005056267763%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=mUclh7UDnl4BX4nIirdM5FFbtR9SKMC01iWHDMNqUtQ%3D&reserved=0 <https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fapps.juniper.net%2Ffeature-explorer%2Ffeature-info.html%3FfKey%3D6620%26fn%3DEthernet-over-MPLS%2520&data=04%7C01%7Cgiuliano%40wztech.com.br%7Ca894125d52644bd4059a08d901135ff1%7C584787b077bd4312bf8815412b8ae504%7C1%7C0%7C637542005056267763%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=cm1%2FqV2VK7dmi9ZV2Xhg%2BnKRTdyzeg30E8uCW%2BY1e%2FA%3D&reserved=0(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?
