5.7 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
