Reference Guide for the Model RT210/RT211 ISDN Routers
3-12 Configuring the Router
To ensure that the router knows that routes are learned over an ISDN path, you must enter an ISDN
number in the configuration path. Any routes learned through this path are displayed with an I after
the routing protocol R (RIP) in the routing table display.
To connect to a router using PPP, you must first configure a PPP path.
Configuring a PPP Path
To configure a PPP path, follow these steps:
1. Enter CO PA to display the Configure Paths menu.
2. Enter ADD to add a PPP path.
3. Enter the name of the remote router in the Name field.
This must match the User ID that is supplied by the remote router if calls are to be made to
your router using authentication.
4. Tab to select the ISDN1 field and enter the ISDN phone number of the remote router.
If the connection is on a 56 KBps line, enter the # symbol before the ISDN number.
5. Tab to select the PPP Prof field and press the space bar until you have selected the
appropriate authentication option.
For further information on authentication and the option that you need, refer to the tables in
Appendix E, “PPP Authentication Profiles.”
If using PAP authentication, select the PPP OutgoingPW field and enter the password to
be used when calling the remote router.
If using PAP authentication, select the PPP incoming PW field and enter the password to
be used by the remote router when calling your router.
If using CHAP authentication, select the PPP Secret field and enter the password to be
used when connecting to the remote router.
6. Enter the IP address in the IP ADDR&MASK field only if the link is to be numbered.
The path operates as unnumbered with the IP ADDR&MASK left at its default value (0.0.0.0),
and no identifying network addresses are negotiated when the link is set up. Any IP data
packets have the LAN01 IP address as their source address. Any other value entered in the
field are sent during link establishment to negotiate a numbered link except for a Single Host
Address. For more information on a Single Host Address, refer to Operating with a Single IP
Address” on page 3-14.
