Inserting the DHCPv6 Interface Identifier into DHCPv6 Packets
You can configure DHCPv6 relay agent to insert the DHCPv6 interface identifier, using
option 18, in the packets that the relay sends to a DHCPv6 server. You can configure the
option 18 support at either the DHCPv6 global level or the DHCPv6 group level.
When you configure option 18 support, you can optionally include the following additional
information:
•
Prefix—Specify the prefix option to add a prefix to the interface identifier. The prefix
can be any combination of hostname and routing instance name.
•
Interface description—Specify the use-interface-description option to include the textual
interface description instead of the interface identifier. You can include either the device
interface description or the logical interface description.
NOTE: If you specify one of the optional configurations, and the specified
information does not exist (for example, if there is no interface description),
DHCPv6 relay ignores the optional configuration and inserts the default
interface identifier in the packets.
To insert the DHCPv6 interface identifier (option 18) in DHCPv6 packets:
1. Configure the DHCPv6 relay to include option 18.
[edit forwarding-options dhcp-relay dhcpv6]
user@host# edit relay-agent-interface-id
2. (Optional) Specify the prefix to include in option 18.
