Hello, I have one x460-t who has a VPLS to X670. A problem is been seeing on the X460 side, that when I do a show fdb on the vlan that is untagged to a port with the VPLS, there is alot of unwanted MAC that are not showed on the X670. It looks like multicast traffic are forwarded to that VPLS but it wasn't suppose to. The x460 version is 15.5.4.2. X670 is 15.5.3.4 patch1-5. Is that possible to be a version mismatch problem? x460 Configuration
