Information Needed for Configuration Chapter 1 Basic Router Configuration Information Needed for Configuration You need to gather some or all of the following information, depending on your planned network scenario, prior to configuring your network • If you are setting up an Internet connection, gather the following information: - Point-to-Point Protocol (PPP) client name that is assigned as your login name - PPP authentication type: Challenge Handshake Authentication Protocol (CHAP) or Password Authentication Protocol (PAP) - PPP password to access your Internet service provider (ISP) account - DNS server IP address and default gateways • If you are setting up a connection to a corporate network, you and the network administrator must generate and share the following information for the WAN interfaces of the routers: - PPP authentication type: CHAP or PAP - PPP client name to access the router - PPP password to access the router • If you are setting up IP routing: - Generate the addressing scheme for your IP network. - Determine the IP routing parameter information, including IP address, and ATM permanent virtual circuits (PVCs). These PVC parameters are typically virtual path identifier (VPI), virtual circuit identifier (VCI), and traffic shaping parameters. - Determine the number of PVCs that your service provider has given you, along with their VPIs and VCIs. - For each PVC determine the type of AAL5 encapsulation supported. It can be one of the following: AAL5SNAP-This can be either routed RFC 1483 or bridged RFC 1483. For routed RFC 1483, the service provider must provide you with a static IP address. For bridged RFC 1483, you may use DHCP to obtain your IP address, or you may obtain a static IP address from your service provider. AAL5MUX PPP-With this type of encapsulation, you need to determine the PPP-related configuration items. • If you plan to connect over an ADSL or G.SHDSL line: - Order the appropriate line from your public telephone service provider. For ADSL lines-Ensure that the ADSL signaling type is DMT (also called ANSI T1.413) or DMT Issue 2. For G.SHDSL lines-Verify that the G.SHDSL line conforms to the ITU G.991.2 standard and supports Annex A (North America) or Annex B (Europe). Once you have collected the appropriate information, you can perform a full configuration on your router, beginning with the tasks in the "Configuring Basic Parameters" section.
