Dear Adam, yeah, forget about LACP - the bigger problem is all the LLDP and STP stuff, that gets interpreted at the UNI port. LACP is a bad example - but there are many other frames and protocols, which must work. Could be that a customer wants to run MPLS+LDP on his VLL (for whatever reason ...).

Not 100% sure the Juniper EX does 25G, now that I think of it. Yeah, EX4650 it does: 48x 1/10/25G + 6x 100G + MPLS It also supports Ethernet over MPLS (at least they say here: https://www.juniper.net/documentation/en_US/junos/topics/topic-map/mpls-over view.html#id-mpls-feature-support-on-qfx-series-and-ex4600-switches) but at some of their sites they mention, that MPLS-based CCC are not support: https://www.juniper.net/documentation/en_US/junos/topics/topic-map/mpls-over view.html#jd0e2531 " ... MPLS-based circuit cross-connects (CCC) are not supportedonly circuit-based pseudowires are supported. ..." There is also the QFX5120-48Y - 48x 1/10/25G + 8x 100G + MPLS In the past QFX wasn't the best idea for MPLS topics ... has this changed? > and Arista has, oh, at least half a dozen boxes of various spec that comply, too. Yeah, I already know them (do have some older 7050S). The call it "VXLAN P2P Pseudowire", but there is absolutely nothing in there CLI documentation :(. Looks like the feature is only support on the 7280 platform. Possible options: 7280SR2-48YC6 Do you have any experience with what they call "VXLAN P2P Pseudowire"? I can't even find a config example on the net :( thanks & best regards Jürgen -----Ursprüngliche Nachricht----- Von: Adam Thompson [mailto:[email protected]] Gesendet: Dienstag, 7.

For your requirements, although I hesitate to recommend them for enterprise/carrier use, Miktotik's EoIP protocol does a much better job of this than most "carrier-grade" implementations. Otherwise, Juniper and Arista both come to mind, Juniper has the EX4650 that matches your h/w specs, and Arista has, oh, at least half a dozen boxes of various spec that comply, too. Not 100% sure the Juniper EX does 25G, now that I think of it.
