Creating Pppoe Tunnels - Zhone zNID-GPON-2402 Configuration Manual

Creating PPPoE tunnels

PPPoE is defined for the uplink port of a VLAN. In this mode, the zNID
24xx will establish a PPPoE session with a server on behalf of the client
connected to the configured port. Each VLAN can have 1 PPPoE session.
The configuration of the PPPoE session requires only a few parameters:
•
user name
•
password
•
authentication method
When in the PPPoE mode, the uplink port will always perform the NAT
function. This means that the LAN portion will also have the DHCP server
enabled. Depending on how the LAN ports need to be configured, the PPPoE
connection will be defined to be either Bridged or Routed.
The zNID 24xx supports PAP, CHAP or MS CHAP. The zNID 24xx can be
set to "auto" in which case it will use what ever method the server uses.
•
PPPoE Bridged Mode
In PPPoE Bridged Mode mode, a single DHCP server will provide
addresses for the devices connected to any of the LAN ports. All ports
will be members of the same IP subnet. They are also all members of the
same VLAN.
•
PPPoE Routed Mode
In PPPoE Routed Mode mode, there is a DHCP server for each LAN port.
Each port is on a different IP subnet. This method should be used when
the ports are connected to different customers, such as different
apartments that are served from a single zNID 24xx.
