Configuring the DSL Router

Numbered DSL Interface

In this scenario, the hosts attached to the DSL router's Ethernet interface are on a different logical network than the core router. The DSL router is the next hop router for the hosts. The upstream next hop router for the DSL router is the core router.

The hosts can be assigned IP addresses on the network attached to the DSL router's Ethernet interface. The upstream next hop router is assigned an address on a different logical network than the hosts.

Actions required to configure the DSL router interfaces in this scenario:

HAssign IP address to Ethernet interface: eth1

HAssign IP address to DSL interface: dsl1

HAssign upstream next hop router

Unnumbered DSL Interface

In this LAN extension application scenario, the hosts connected to a corporate network for virtual office connection or teleworkers want to look like they are on the same network as the core router. The core router will be the next hop router for the hosts.

Actions required to configure the DSL router interfaces in this scenario:

HAssign IP address to Ethernet interface: eth1

HSpecify the DSL interface as unnumbered: dsl1

HAssign upstream next hop router

HEnable Proxy ARP for both the eth1 and dsl1 interfaces

HDisable scoping on the DSL card at the DSLAM/GranDSLAM chassis
