For your requirements, although I hesitate to recommend them for enterprise/carrier use, Miktotik's EoIP protocol does a much better job of
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 ...). this than most "carrier-grade" implementations. Not at wirespeed ... and not without causing other issues (single thread load, etc).
Juniper has the EX4650 that matches your h/w specs,... 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:athompson@merlin.mb.ca] 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.

Dear folks,
have anyone already tried to run VXLAN/EVPN + Bridge Layer 2 Protocol Tunneling on Cumulus Linux as an replacement for classic MPLS L2VPN/VPWS (xconnect, l2circuit, VLL) ?
I need to provide transparent Ethernet P2P virtual leased lines to my customers and these have to support stuff like LLDP, STP, LACP, etc. The transport L2 network is not THAT big: max hops between VTEP is 4.
Anyone have suggestions for the below hardware request? #) 1-3U L2/L3 box #) 48x SFP28 / 1/10/25G #) 6x QSFP28 / 100G #) VXLAN/EVPN with L2 tunneling support or #) MPLS VPWS/l2circuit #) Dual PSU
thanks & best regards Jürgen
