5.6 Technical Reference

The following section contains additional technical information about the P-
2812HNU-51c features described in this chapter.
Encapsulation
Be sure to use the encapsulation method required by your ISP. The P-2812HNU-
51c can work in bridge mode or routing mode. When the P-2812HNU-51c is in
routing mode, it supports the following methods.
IP over Ethernet
IP over Ethernet (IPoE) is an alternative to PPPoE. IP packets are being delivered
across an Ethernet network, without using PPP encapsulation. They are routed
between the Ethernet interface and the WAN interface and then formatted so that
they can be understood in a bridged environment. For instance, it encapsulates
routed Ethernet frames into bridged Ethernet cells.
PPP over Ethernet
Point-to-Point Protocol over Ethernet (PPPoE) provides access control and billing
functionality in a manner similar to dial-up services using PPP. PPPoE is an IETF
standard (RFC 2516) specifying how a personal computer (PC) interacts with a
broadband modem (DSL, cable, wireless, etc.) connection.
For the service provider, PPPoE offers an access and authentication method that
works with existing access control systems (for example RADIUS).
