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 93 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 SAM1316-22'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 SAM1316-22’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 SAM1316-22's management IP address should not be in the same subnet
range of any RPVC and RPVC domain. It will make the SAM1316-22 confused if
the SAM1316-22 receives a packet with this IP as destination IP.
• The SAM1316-22’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.
• The subnet range of any RPVC and RPVC domain must be unique.
