POS Interface Bridge
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 negotiation
