Well luckily we have MEF to set expectations about ones EPL/EVPL/EPLAN/EVPLAN performance. (and formal SLA contracts describing every single aspect of the service and its performance). Anyways, when I was designing these the back in the days when it was cool and demand was high, customers (other carriers) were getting MTU9100 (to fit customers MTU9000), the whole CFM & LFM shebang (to the point made earlier in the thread that the link should go down on both ends -like it’s the case with a wave) and sub 50ms convergence in case something when wrong inside our backbone. We as a provider got more $$$ from single investment to our wave/fiber, but our customers could enjoy p2p links on par with wave for less $. adam From: NANOG <nanog-bounces+adamv0025=netconsultings.com@nanog.org> On Behalf Of Robert Raszuk Sent: Friday, July 17, 2020 10:50 AM To: Mark Tinka <mark.tinka@seacom.com> Cc: nanog@nanog.org Subject: Re: BFD for long haul circuit
Unfortunately not.
Fortunately .... very fortunately Mark. L2VPNs running on someone's IP backbone sold by many as "circuits" has many issues ... stability, MTU blackhols, random drops - and that is pretty much the same all over the world :( Very unfortunate technology just to mux more users and get more $$$ from single investment.

You have any backhauls, that is running over an L2 xconnect ? I’m facing issue only on the backhaul link over a l2vpn ckt. Unfortunately not. All our backbones are either over dark fibre or EoDWDM.
