1758677Traffic flooding for MAC addresses programming failure
Product-Group=evo		Issue 1: On QFX5K and EX platforms, traffic flooding will be observed for MAC addresses not getting programmed in hardware in the VXLAN (Virtual Extensible LAN) environment with VPLAG (Virtual Chassis Port Link Aggregation) configured and BGP (Border Gateway Protocol) flaps. This issue happens when hardware write by L2ALM to PFE fails, and during re-sync, SVLBNH (shared VXLAN load balancing next hop) info is not sent to PFE/hardware. Issue 2: On all Junos platforms, l2alm sends a delete request for control MAC addresses to l2ald after multiple hardware sync failures.
