Configuring DHCPv6 Server Addresses on an Interface
You can configure DHCPv6 server IP addresses on an interface. When an inbound DHCP BOOTREQUEST
packet arrives on the interface, the relay agent forwards the packet to all DHCPv6 server IP addresses specified.
The relay agent forwards replies from all DHCPv6 servers to the host that sent the request.

Purpose
Enters global configuration mode.
Enables VRF support for the DHCPv6 relay agent. The no
option disables this behavior.
Causes the DHCPv6 relay agent to insert virtual subnet
selection (VSS) details as part of the vendor-specific option.
The no option causes the DHCPv6 relay agent to insert VSS
details as part of the VSS option (68), which is defined in
RFC-6607. This command is useful when you want to use
DHCPv6 servers that do not support RFC-6607 but allocate
IPv6 addresses based on the client VRF name.
Displays the DHCPv6 relay configuration.
Displays the DHCP configuration.
Copies the running configuration to the startup
configuration.
