This feature allows the leaking of connected routes from one VRF (the source VRF) to another VRF (the destination VRF)

VRF 4.22.1F Leaking Connected

Previously, when both “ipv6 nd proxy prefix connected” and VXLAN is configured for a VLAN interface, and the router received a Neighbor solicitation (NS) with an IPv6 address within the connected prefix of the router, the router replied with the interface physical (or virtual-router if VARP is configured) mac address as long as the NS is received on a local (front-panel) port. This feature extends the behavior to also include the NS received from the VXLAN tunnel.
