Dynamic individual users
IPoE defines the following dynamic individual users:
DHCP user—Sends DHCP packets to trigger IPoE session establishment.
IPv6-ND-RS user—Sends IPv6 ND RS packets to trigger IPoE session establishment.
Unclassified-IP user—Sends packets other than DHCP and IPv6 ND RS packets to trigger
IPoE session establishment.
•
Static individual users
Static individual users trigger IPoE session establishment by sending IP packets or ARP
packets. If an IP packet matches a manually configured IPoE session, the BRAS authenticates
the user and establishes an IPoE session.
Leased users
Leased users include the following types:
•
Interface-leased user—Represents hosts that rent the same interface.
•
Subnet-leased user—Represents hosts that rent a subnet of an interface.
•
L2VPN-leased user—Represents hosts that rent the same interface on an L2VPN network.
The BRAS automatically uses the credentials configured for a leased user to perform authentication.
Users are not required to send IP packets to trigger authentication.
IPoE session
IPoE sessions include dynamic and static sessions.
Dynamic IPoE session
IPoE sessions established for dynamic individual users are dynamic IPoE sessions.
The BRAS disconnects a dynamic IPoE session in one of the following cases:
•
The AAA-authorized service expires.
•
The AAA server logs out the user.
•
The user traffic is less than the authorized traffic during the idle-timeout time.
•
The BRAS cannot detect the user after the number of detection attempts reaches the
maximum.
•
The IP address lease expires.
•
The IPoE session is restarted.
•
The access interface goes down.
Static IPoE session
IPoE sessions established for static individual users, interface-leased users, subnet-leased users,
and L2VPN-leased users are static IPoE sessions.
IPoE static individual sessions include interface-level static individual sessions and global static
individual sessions.
•
Interface-level static individual sessions—The BRAS creates a static individual session
based on configured information after you enable IPoE on an interface in up state. The BRAS
initiates user authentication based on the configured username and password upon receiving
IP or ARP packets from users. Interface-level static IPoE sessions can only be deleted
manually at the CLI.
•
Global static individual sessions—On an IPoE-enabled interface in up state, the BRAS
initiates authentication based on the configured username and password upon receiving IP or
ARP packets from users. The BRAS creates a global static individual session only when the
authentication succeeds.
