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 $$$ from single investment to our wave/fiber, but our customers could enjoy p2p links on par with wave for less $. adam From: NANOG <[email protected]> On Behalf Of Robert Raszuk Sent: Friday, July 17, 2020 10:50 AM To: Mark Tinka <[email protected]> Cc: [email protected] Subject: Re: BFD for long haul circuit > Unfortunately not. Fortunately .... very fortunately Mark. L2VPNs running on someone's IP backbone sold by many as "circuits" has many issues ... stability, MTU blackhols, random drops - and that is pretty much the same all over the world :( Very unfortunate technology just to mux more users and get more $$$ 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.
