Overview of IPoE Access
This section describes basic concepts of IP over Ethernet (IPoE) access, helping you quickly configure IPoE access.
In IPv4 network access where a user terminal connects to a BRAS's Ethernet interface through a Layer 2 device, such as a LAN switch, the user IP packets are encapsulated into IPoE packets by the user terminal's Ethernet interface before they are transmitted to the BRAS through the Layer 2 device. IPoE is an access mode that allows the BRAS to perform authentication and authorization on users and user services based on the physical or logical user information carried in IPoE packets, such as the MAC address, VLAN ID, and Option 82.
Simple access mode that does not need dial-up software on the client
More applicable to multicast services
Services are interrupted if the memory size of the master main control board is inconsistent with that of the slave main control board.
