4 Use the adsl rpvc arp commands to view the Address Resolution Protocol table of
IP addresses of CPE devices using 2684 routed mode and configure how long the device
is to store them.
5 For upstream traffic: Since the subscriber's device will not send out a MAC address, after
the IES-612-51A reassembles the Ethernet packets from the AAL5 ATM cells, the IES-
612-51A will append the routed mode gateway's MAC address and the IES-612-51A's
MAC address as the destination/source MAC address.
6 For downstream traffic: When the IES-612-51A sees the destination IP address is
specified in the RPVC (or RPVC domain), the IES-612-51A will strip out the MAC
header and send them to the corresponding RPVC.
53.7.1 2684 Routed Mode Example
The following figure shows an example RFC 2684 (formerly RFC 1483) routed mode set up.
The gateway server uses IP address 192.168.10.102 and is in VLAN 1. The IES-612-51A uses
IP address 192.168.20.101. The subscriber’s device (the CPE) is connected to DSL port 1 on
the IES-612-51A 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.
Figure 269 2684 Routed Mode Example
Note the following.
• The CPE device’s WAN IP (192.168.10.200 in this example) must be in the same subnet
as the gateway’s IP address (192.168.10.102 in this example).
• The IES-612-51A's management IP address can be any IP address, it doesn't have any
relationship to the WAN IP address or routed gateway IP address.
