PDF user manual for CopperEdge 150

,31HWPRGHOIn the IP netmodel, the end points of the VCs must be manuallyconfigured for each of the stages on the link, but this time, eachof the interfaces requires an IP address. (In the diagram below,all addresses are private, although they could be public.)The VC going from the Telco router to the WAN port on theCE150 must have an IP address at each end. Its endpointsmust be on different subnets. The WAN VC and the DSL portalso must have IP addresses. They also must be on differentsubnets. Finally, the DSL port and its downstream hosts musthave IP addresses, but they must be on the same subnet.Since the CPE is in bridge mode, it doesn’t require an IP address.The DSL port, not the upstream CPE port, is the gatewayfor hosts on the LAN. But, since the CE150 in the IP netmodelis in router mode, it sends packets coming upstream from itsDSL ports to its WAN VC based on destination addresses in thepackets. It sends packets coming downstream from its WAN VCto the proper DSL ports based on destination addresses.For each of the DSL ports with G.dmt and G.lite CPEs connectedto them, part of the configuring process must be repeated.New DSL VCs must be created on each DSL port.In the following diagram, only one DSL and one WAN port appear.In the procedure on the following pages, first a WAN VCwith an IP address of 192.168.20.2 will be created; then a DSLVC with an IP address of 10.10.1.1. Finally, the default IP routeon the CE150 will be set. Configuration of addresses on the Telcorouter and downstream hosts will not be shown.&RSSHU(GJH,QVWDOODWLRQDQG2SHUDWLQJ*XLGH
