DHCPv6 Local Server Overview
The DHCPv6 local server is compatible with the DHCP local server and the DHCP relay
agent, and can be enabled on the same interface as either the extended DHCP local
server or DHCP relay agent.
The DHCPv6 local server provides many of the same features as the DHCP local server,
including:
•
Configuration for a specific interface or for a group of interfaces
•
Site-specific usernames and passwords
•
Numbered Ethernet interfaces
•
Statically configured CoS and filters
•
AAA directed login
•
Use of the IA_NA option to assign a specific address to a client
When a DHCPv6 client logs in, the DHCPv6 local server can optionally use the AAA service
framework to interact with the RADIUS server. The RADIUS server, which is configured
independently of DHCP, authenticates the client and supplies the IPv6 prefix and client
configuration parameters.
The client username, which uniquely identifies a subscriber or a DHCP client, must be
present in the configuration in order for DHCPv6 local server to use RADIUS authentication.
You can configure DHCPv6 local server to communicate the following attributes to the
AAA service framework and RADIUS at login time:
•
Client username
•
Client password
Based on the attributes that the DHCPv6 local server provides, RADIUS returns the
information listed in Table 10 on page 40 to configure the client:

To configure the extended DHCPv6 local server on the router (or switch), you include
the dhcpv6 statement at the [edit system services dhcp-local-server] hierarchy level.
