That TAC case is: 2012-0129-0118. I was able to get a production version of the Active / Active MC-LAG with a Juniper EX2200C switch.Window replacement bellemont azIn the example, the LAG was used as a layer 3 link. Just as with other interfaces on an MX, it is possible to use the link in a different way. For instance, you could use: set interfaces ae0 encapsulation vlan-tagging set interfaces ae0 encapsulation flexible-ethernet-services. The above configuration will get you started.
