Hello, I had to do the same migration than last time last thursday. - Shut down the two former ethernet links to our former datacenter - Turn on the new ethernet link - Change the default gateway to the new link Everything worked fine after the migration (oowh) But since last monday I can ping (from an other location each gateway on the branch switch stack meraki (MS410) but when I ping the endpoints, or even if I ping the endpoints from the local gateway on the meraki switch I've got very high latency. I can't understand how it can be so unstable 0 0/ 100 = 0% | 1 1ms 0/ 100 = 0% 0/ 100 = 0% 10.20.x.x (HQ gateway MS410) 0/ 100 = 0% | 2 4ms 0/ 100 = 0% 0/ 100 = 0% 10.0.x.x (DC Firewall <> HQ interco) 3/ 100 = 3% | 3 8ms 3/ 100 = 3% 0/ 100 = 0% 10.0.x.x (Branch Meraki MS410) 52/ 100 = 52% | 4 465ms 55/ 100 = 55% 0/ 100 = 0% 10.10.x:x (Endpoint) Not sure if it's clear enough, and sorry about my english 🙂
