IPv6

Route-based proxy neighbor discovery for VM gateways (QFX5110, QFX5120-32C, QFX5120-48T, QFX5120-48Y, QFX5120-48YM, QFX5200, QFX5210 switches)—Use route-based proxy neighbor discovery to address network connectivity issues between hosts on different physical networks. This approach enables the gateway to send its MAC address to the source host, facilitating communication over routes instead of Layer 2 switching. By maintaining host routes in the routing table, you can ensure reachability and redistribute routes into BGP or interior gateway protocols (IGPs). Note that, the QFX5000 series supports proactive Address Resolution Protocol (ARP) detection, but doesn’t support proactive IPv6 neighbor learning. You can use this method only with default routing tables.
