Prestige 641 ADSL Internet Access Router

Follow the instructions in the following table to configure TCP/IP parameters for the Ethernet port.

Table 3-2 TCP/IP Ethernet Setup Menu Fields

Field	Description	Example

TCP/IP Setup
IP	Enter the (LAN) IP address of your Prestige in dotted decimal	192.168.1.1
Address	notation	(default)
IP Subnet Mask	Your Prestige will automatically calculate the subnet mask based	255.255.255.0
	on the IP address that you assign. Unless you are implementing
	subnetting, use the subnet mask computed by the Prestige
RIP	Press the space bar to select the RIP direction from Both/In	Both
Direction	Only/Out Only or None.	(default)
		(default)
Version	Press the space bar to select the RIP version from RIP-1/RIP-	RIP-1
	2B/RIP-2M.	(default)
		(default)

When you have completed this menu, press [Enter] at the prompt [Press ENTER to Confirm…] to save your configuration, or press [Esc] at any time to cancel.

3.6VPI & VCI

Be sure to use the correct Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI) numbers supplied by the Telephone Company. Please see VPI & VCI in Appendix B for more information.

3.7Multiplexing

There are two conventions to identify what protocols the virtual circuit (VC) is carrying. Be sure to use the multiplexing method required by your ISP.

3.7.1VC-based multiplexing

In this case, by prior mutual agreement, each protocol is assigned to a specific virtual circuit, e.g., VC1 carries IP, VC2 carries IPX, etc. VC-based multiplexing may be dominant in environments where dynamic creation of large numbers of ATM VCs is fast and economical.

3.7.2LLC-based multiplexing

In this case one VC carries multiple protocols with protocol identifying information being contained in each packet header. Despite the extra bandwidth and processing overhead, this method may be advantageous if it
