POS Bridge Overview
Bridge function of the POS interface covers: layer 3 function and
transparent transmission of the bridge interface.
Layer 3 function of the bridge interface indicates that the PPP
link is directly connected with the Ethernet with BCP
encapsulation. The POS layer 3 interface using BCP
encapsulation can serve as an Ethernet interface and has
attributes of the Ethernet interface, such as ARP learning.
Transparent transmission function of the POS bridge
interface is implemented through V_Switch functions. With
the V_Switch forwarding table, transparent transmission is
available between the POS interface and the Ethernet and
ATM interfaces.
As a link layer protocol, the PPP is responsible for establishing,
deleting and maintaining layer 2 links. PPP negotiation process is
as follows: LCP negotiationÆEstablish (establish links)ÆCHAP or
PAP authentication.
