Release Information

Statement introduced in Junos OS Release 9.1.

Support for DHCPv6 added in Junos OS Release 17.2 for MX Series Routers.

Description

Specify that the MAC address from the client PDU be concatenated with the username during the subscriber authentication or DHCP client authentication process.

For DHCPv6 clients, because the DHCPv6 packet format has no specific field for the client MAC address, the MAC address is derived from among several sources with the following priority:

  • Client DUID Type 1 or Type 3.

  • Option 79 (client link-layer address), if present.

  • The packet source address if the client is directly connected.

  • The link local address.
