Hi, I am guessing there is a preferred route towards xe-2/0/14. Could you show the routes. You could try increasing the metric/cost of the xe-2/0/14 interface so the metric is higher than the other ge...

It seems 2 is a pretty low number for the mac move limit. all the examples I see of the configuration are set to 4 or 5 as the limit. Perhaps you just need to increase the allowed number?
