Policy-to-Ethernet IP RoutingYou can configure DSL interfaces for policy IP routing to theCE150’s Ethernet port. To do so, set the NetModel, IpAddr, Net-Mask, Encapsulation, DestPii, and farEndAddr objects in theDSL port’s cmIface entry. You must set the DestPii to a CE150Ethernet port, usually 1.3.1. You must also set the DSL port’sfarEndAddr object to the next hop IP address on the Ethernetsubnet to receive the forwarded packets. Each DSL port canspecify a different farEndAddr on the same Ethernet interface.In this forwarding mode, the CE150 forwards inbound DSLpackets that are not addressed to the DSL’s own IP address, tothe specified Ethernet port and next hop IP address. For policyrouting, the CE150 does not consult any routing table to forwardreceived packets. For example:CRAFT> set cmiface[1.4.1] netmodel=ip ipaddr=192.168.1.1netmask=255.255.255.0 encapsulationtype=rfc1483destpii=1.3.1 farendaddr=172.16.1.1Ethernet and WAN VCs do not support policy routing.9:$11HWPRGHOThis section assumes you are familiar with the networking conceptsof Copper Mountain’s VWAN netmodel. It provides detailsof how to configure the VWAN functions of the CE150.VWAN is the simplest mode to configure for DSL interfaces. Todo so, set the NetModel, Encapsulation, and DestPii. You mustspecify a WAN VC or an Ethernet port for the DestPii. If only oneDSL port refers to a given WAN VC, both interfaces are in VWANpoint-to-point mode. If two or more DSL ports refer to the sameWAN VC, all the interfaces in the VWAN group are in VWANbridge mode. The CE150 automatically selects the FwdModebased on the given configuration. For example:CRAFT> set cmiface[1.4.1] netmodel=vwanencapsulationtype=rfc1490 destpii=1.2.1.61WAN VCs do not need to be configured for VWAN mode becausethey assume VWAN mode automatically when referenced byVWAN DSL ports.WAN VC and Ethernet interfaces cannot be configured as membersof a WAN group.&RSSHU(GJH,QVWDOODWLRQDQG2SHUDWLQJ*XLGH
