&RQILJXULQJ3ROLF\5RXWHG'6//LQNVDSL links may be policy routed to a virtual circuit on a CE150WAN port, or to a specific host device on a LAN over the CE150Ethernet port.,33ROLF\2YHU:$1To configure a DSL link for policy routing over a WAN link, configurethe DSL link (set cmiface) to specify its IP address, netmask, and a DestPii. The DestPii includes shelf number, slot,port and the virtual identifier (Frame Relay DLCI or ATM virtualcircuit number), in the full PII format as shown in the followingsample configuration. For example:Group: cmIfaceTableInstance: [1.4.1.0]PII = 1.4.1.0IfIndex = 1.4.1.0NetModel = IPIpAddr = 192.168.1.1NetMask = 255.255.255.0MacAddr = 0.60.58.0.0.bBurnedInMacAddr = 0.60.58.0.0.bFarEndAddr = 0.0.0.0DestPii = 1.2.1.32CMCPCompatible = YesEncapsulationType = rfc1483FwdMode = IP PolicyPix = 27As shown in this example, policy-routed DSL links do have IPaddresses and subnet masks, because packets are routed tothem with full-IP routing.Packets forwarded in IP-Policy mode are capable of generatingthe IETF standard TTL Exceeded ICMP error message if thepackets expire before reaching their destination (V1.6 and later).This capability enables use of standard TraceRoute diagnosticutilities.Note, however, that because outbound policy-routed packetsbypass the CE150 routing table, a TraceRoute sequence cannotidentify the CE150 leg of the route. To resolve the hop to andfrom the CE150, you can add an entry to the routing table thatwill let the ICMP error message track through and identify theroute segment from the WAN VC, through the CE150, to theDSL port/CPE.&KDSWHU5RXWLQJ)RUZDUGLQJ0DQDJLQJ/LQNV
