Subscriber Services: Vendor-specific information in DHCPv4 & DHCPv6 relay

You can add a hostname, location (such as a unique connection identifier), or both in DHCP control packets sent over server-facing interfaces. For DHCPv4 relays, the feature leverages option 82, suboption 9, to provide the vendor-specific information. For DHCPv6 relays, it is added under the vendor-specific option (17). This feature can be useful when used with operator-developed tools for troubleshooting DHCP servers and providing service assurances. For example, a central DHCP server can log the information, and operators can query a single entity to track and troubleshoot subscriber IP information and network attachment points. To configure vendor-specific information, add a hostname, location, or both at the [edit forwarding-options dhcp-relay relay-option-82 vendor-specific host-name] or [edit forwarding-options dhcp-relay relay-option-82 vendor-specific location] hierarchy level.
