Usage Guidelines
You can use the ipv6 dhcp relay option vpn command to relay DHCPv6 requests that arrive on an interface
in one VRF to a DHCPv6 server in a different VRF.
The ipv6 dhcp relay option type cisco command 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.
The ipv6 dhcp relay source-interface command configures the source interface for the DHCPv6 relay. By
default, the DHCPv6 relay agent uses the relay agent address as the source address of the outgoing packet.
