LACP is intended as link aggregation for the two devices that are directly connected together and so LACP packets are usually interpreted as "local" only. Most gear will give you the option to tunnel L2 control packets, but only on a P2P type service. Optus might work depending on product and configuration, I suspect nbn will never work.</div></blockquote><div><br></div><div>Agree. More broadly it can end in tears if customers rely on and are allowed to rely on undocumented service feature capabilities, because once you allow a customer to try it and use an undocumented service capability, and it works, and then they rely on it, and it can be hard or impossible to take it away if you need to.</div><div><br></div><div>(It's a long story, however in the distant past I've had to work on taking away customers' ability to run STP over their VPLSes, if they happened to be, because we needed to use it internally to prevent forwarding loops while LACP was negotiating on a specific vendor's equipment that had followed the IEEE's specs to the letter (after that experience, you realise most vendors aren't entirely implementing LAG/LACP fully IEEE compliantly).</div><div><br></div><div>Running STP/RSTP wasn't a supported service capability. It would work on a VPLS that was only using our access circuits, however if the customer's VPLS had at least one 3rd party access circuit, then we knew they weren't running STP.</div><div><br></div><div>The lesson of the story is don't allow customers to actively "suck it and see" for unsupported service capabilities. The technical product spec provided to customers should be the only things that work, so you definitely know what customers are and are not running over your service.)<br><br>Regards,</div><div>Mark.</div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto"><div dir="auto"><br></div><div dir="auto">What are you trying to achieve and are there other options you should consider instead ?</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, 9 Nov 2023, 22:00 Max Soukhomlinov, <<a href="mailto:maxs@intellectit.com.au" target="_blank">maxs@intellectit.com.au</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
