I ran into similar limitations with the same version. I have tried both MAC synchronization and VRRP. When packets hit the "wrong" node (the one that didn't learn the neighbor information), they are not forwarded. See: https://lists.gt.net/nsp/juniper/60956#60956 I got additional private feedback from people with similar issues (MC-LAG and L3 forwarding). I didn't try to involve JTAC. -- Don't stop at one bug. - The Elements of Programming Style (Kernighan & Plauger) _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
