DHCPv6 relay agent

Supporting VXLAN topologies or inter-VRF deployment

When deploying EVPN VXLAN or inter-VRF topologies where the source VRFs for the DHCP and DHCP client are different, it is recommended that you install the DHCPv6 server in the underlay so that there is only one instance of the DHCPv6 server serving overlay clients.
