Each ARP/ND packet into a switch may generate an update for the switch ARP/Neighbor table and this update may need to be synchronized with the MLAG peer when VXLAN is configured. Prior to this feature, these updates (on a VXLAN setup) are synchronized by sending an UDP packet (one packet per update) containing the IP/MAC/VLAN information from the MLAG peer where the ARP/ND packet is received to the other MLAG peer. 

This feature makes a switch act as a neighbor discovery proxy for an IPv6 subnets. It can be used in conjunction with BUM

This configuration command features an IPv6 Neighbor Discovery (ND) option (called Boot File URL (BFURL) option)

LDP per-neighbor authentication provides greater flexibility in the authentication of LDP routers in a network. Individual routers or groups of routers may be configured with different passwords to enhance security and to ensure certain routers do not exchange MPLS

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.
