3. Configuring the DSL Router

Ethernet Interface

—The Ethernet interface is a 10/100BaseT interface that automatically negotiates the rate to be used, 10 Mb or 100 Mb. If all Ethernet-attached devices are capable of operating at 100 Mb, the router defaults to 100 Mb. Otherwise, it operates at 10 Mb.

—The interface can be configured for either DIX or IEEE 802.3 frame format. When configured to use IEEE 802.3 format, SNAP encapsulation is used, as specified in RFC 1042.

—The interface has a unique MAC address, assigned before the router is shipped.

—Hotwire 6302 IDSL and 6342 SDSL Routers have a hub configuration (separate pins for input and output) with four Ethernet connectors. The hub acts as a bit-level repeater, with the four Ethernet interfaces logically appearing as one Ethernet communications interface with a single collision domain.

—In router mode, the router only accepts transmissions on the Ethernet interface with the interface’s MAC address, or a broadcast or multicast MAC address.

—In bridge mode, the router accepts all transmissions. This is the default setting.

Interface Identifiers

The following conventions are used for naming router interfaces:

dsl1 (or d0) – Identifier for the DSL interface.

eth1 (or e0) – Identifier for the Ethernet interface.

With exception to primary status, an interface cannot be deleted or changed as long as there is a declared route that uses the interface.

Service Domain IP Address Assignments

Hotwire DSL Routers support multiple service domains.

Service domains are defined by the configured network addresses and subnet masks using the CLI.

Up to four service domain IP addresses and subnet masks can be assigned to each DSL (dsl1) or Ethernet (eth1) interface.

When a numbered interface is designated as the primary interface, that interface’s IP address is used as the Router ID. If no interface is designated as the primary interface, the last numbered interface that was created becomes the Router ID.
