2684 Routed Mode; 2684 Routed Mode Example - ZyXEL Communications IES-1248-51 User Manual

This chapter shows you how to set up 2684 routed mode service.

30.1 2684 Routed Mode

Use the 2684 (formerly 1483) routed mode to have the IES-1248 add MAC address headers to
2684 routed mode traffic from a PVC that connects to a subscriber device that uses 2684
routed mode. You also specify the gateway to which the IES-1248 sends the traffic and the
VLAN ID tag to add. See RFC-2684 for details on routed mode traffic carried over AAL type
5 over ATM.
• Use the
• Use the
The domain is the range of IP addresses behind the subscriber's device (the CPE or
Customer Premises Equipment). This includes the CPE device's LAN IP addresses and
the IP addresses of the LAN computers.
• Use the
addresses of CPE devices using 2684 routed mode and configure how long the device is
to store them.
• Use the
• For upstream traffic: Since the subscriber's device will not send out a MAC address, after
the IES-1248 reassembles the Ethernet packets from the AAL5 ATM cells, the IES-1248
will append the routed mode gateway's MAC address and the IES-1248's MAC address
as the destination/source MAC address.
• For downstream traffic: When the IES-1248 sees the destination IP address is specified in
the RPVC (or RPVC domain), the IES-1248 will strip out the MAC header and send them
to the corresponding RPVC.

30.1.1 2684 Routed Mode Example

The following figure shows an example 2684 routed mode set up. The gateway server uses IP
address 192.168.10.102 and is in VLAN 1. The IES-1248 uses IP address 192.168.20.101. The
subscriber's device (the CPE) is connected to DSL port 1 on the IES-1248 and the 2684 routed
mode traffic is to use the PVC identified by VPI 8 and VCI 35. The CPE device's WAN IP
address is 192.168.10.200. The routed domain is the LAN IP addresses behind the CPE
device. The CPE device's LAN IP address is 10.10.10.10 and the LAN computer's IP address
is 10.10.10.1. This includes the CPE device's LAN IP addresses and the IP addresses of the
LAN computers.
