54.5.1 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-708-22A uses
IP address 192.168.20.101. The subscriber’s device (the CPE) is connected to DSL port 1 on
the IES-708-22A 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 131 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-708-22A'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.
• The IES-708-22A’s management IP address should not be in the same subnet as the one
defined by the WAN IP address and netmask of the subscriber’s device. It is suggested that
you set the netmask of the subscriber’s WAN IP address to 32 to avoid this problem.
• The IES-708-22A's management IP address should not be in the same subnet range of any
RPVC and RPVC domain. It will make the IES-708-22A confused if the IES-708-22A
receives a packet with this IP as destination IP.
• The IES-708-22A’s management IP address also should not be in the same subnet as the
one defined by the LAN IP address and netmask of the subscriber’s device. Make sure you
assign the IP addresses properly.
• In general deployment, the computer must set the CPE device’s LAN IP address
(10.10.10.10 in this example) as its default gateway.
