5. Configuring the FrameSaver DSL Router

FrameSaver DSL Router Overview

The FrameSaver DSL Router supports locally attached hosts or subnets and various customer premises distribution networks that contain IP forwarding devices or routers. The DSL router is shipped as an 802.1d bridge, and it can be configured to simultaneously support IP routing and bridging of all non-IP protocols. The router maintains two routing tables to keep customer data and management data separate.

The router supports Internet Protocol (IP), specified in RFC 791, and Internet Control Message Protocol (ICMP), as specified in RFCs 792 and 950 (with exceptions). It acts as a router or gateway as defined in RFC 791.

The router has two interfaces:

DSL Network Interface

￿Frame relay packets converted to ATM are transported over the DSL line using this interface.

Ethernet

￿This is a 10/100BaseT interface that automatically negotiates the rate. If all attached Ethernet devices support 100BaseT, the router defaults to 100BaseT. Otherwise, the router operates at 10BaseT. The interface has a unique MAC address.

—In router mode, the router accepts on the Ethernet interface only those frames with its own MAC address or a broadcast or multicast MAC address.

—In bridge mode, the router accepts all frames and forwards only ones for which the destination MAC address does not match an entry in the bridge table. This is the default setting.

NOTES:

—The configuration examples included in this chapter cover some common configurations, providing only a few of the possible scenarios.

—IP addresses used in the examples are for illustrative purposes only; they are not intended to be used when configuring your local network.

—Command syntax will vary based on your network setup.

—Configuration commands require an access level of Administrator-Config, and changes need to be saved when being configured to take effect.
