CPA 75x bridge to CPA 75x IP & IPX router -PPP CHAP -IP & IPX networks

Main Site router

>set systemname HQSets the system name of the main router. This system name "HQ" will have to match the user profile in the remote site router for authentication purposes. The system name is sent to the far end router as the userid during ppp authentication.
HQ>set ppp secret client (prompts for chap password) Sets the chap secret that will be used to send the chap magic number to the remote router when the remote router challenges the main router.
Enter Password: happyPrompted to enter the password/secret. "happy" is entered as the chap secret.
ReEnter Password: happy Prompted to reenter the password/secret to ensure consistency.
HQ>set encapsulation pppSets the encapsulation for the user profile default template to ppp.
HQ>set ppp authentication incoming chap Sets the ppp authentication for incoming calls to be forced to authenticate via chap.
HQ>cd lanChange to LAN profile.
HQ:LAN>set bridging offTurns bridging off in the LAN profile.
HQ:LAN>set ip routing onTurns ip routing on in the LAN profile.
HQ:LAN>set ip rip update periodicSends the ip rip tables out the ethernet port every 30 seconds.
HQ:LAN>set ip 198.52.110.254Sets the ip address of the ethernet port.
HQ:LAN>set subnet 255.255.255.0Sets the ip netmask of the ethernet port.
HQ:LAN>set ipx routing onTurns ipx routing on.
HQ:LAN>set ipx framing 802.3Sets the ipx framing type to 802.3.
HQ:LAN>set ipx rip update periodicSends the ipx rip and sap tables out the ethernet port every 60 seconds.
HQ:LAN>set user remoteCreates the user profile "remote". Changes to the user profile "remote". This user profile name has to match the system name of the remote site router. The system name is received from the far end as the userid during ppp authentication.
HQ:remote>set bridging offTurns bridging off in the user profile "remote".
HQ:remote>set ip routing on Turns ip routing on in the user profile "remote".
HQ:remote>set ip 198.51.110.3Sets the ip address of the user profile "remote". The far end router will be in the same ip network as this interface.
HQ:remote>set timeout 120Sets the idle timeout parameter to 120 seconds. If there is no interesting traffic to be forwarded across the ISDN connection for 120 seconds then the call will be disconnected. Because the ipx rip updates are periodic by default on the user profile, the call will never disconnect. There are no ipx filters available at this time.
HQ:remote>set ipx routing onTurns ipx routing on in the user profile "remote".
HQ:remote>set ipx framing 802.3Sets ipx framing type to 802.3.
HQ:remote>set ipx network AFAFSets the ipx network number of the user profile "remote". Note: The far end router will be in the same ipx network as this interface.
HQ:remote>set ppp secret host (promts for chap password)Sets the chap secret that the main router is expecting the remote router's magic number to send when the main router challenges the remote router to authenticate.
Enter Password: docPrompted to enter password/secret. "doc" is enter as the chap secret.
ReEnter Password: docPrompted to reenter password/secret.
HQ:remote>set ppp authentication outgoing chap Sets the ppp authentication on outbound calls to chap. This setting will force bi-directional authentication via chap on the outgoing call basis. When the main router calls the remote router, the main router will force the remote router to authenticate with it via chap.



Remote Site Router

>set systemname remoteSets the system name of the remote router. This system name "remote" will have to match the user profile in the main site router for authentication purposes. The system name is sent to the far end router as the userid in ppp authentication.
remote>set ip 198.51.110.4 Sets the ip address of the INTERNAL profile so that the unit is pingable and can be telneted to, but allows ip to be bridged from the ethernet port to the isdn port. This command, when done at the system prompt, also turns on ip routing in the INTERNAL profile.
remote>set subnet 255.255.255.0Sets the ip netmask of the INTERNAL profile.
remote>set gateway 198.51.110.3Sets the default gateway for the router to the user profile "remote" on the main router.
remote>set ppp secret client (prompts for chap password) Sets the chap secret that will be used to send the chap magic number to the main router when the main router challenges the remote router.
Enter Password: docPrompted to enter the password/secret. "doc" is entered as the chap secret.
ReEnter Password: doc Prompted to reenter password/secret.
remote>set encapsulation ppp Sets the encapsulation for the user profile default template to ppp.
remote>set ppp authentication incoming chapSets the ppp authentication for incoming calls to be forced to authenticate via chap.
remote>set user HQ Creates the user profile "HQ". Changes to the user profile "HQ". This user profile name has to match the system name of the main site router. The system name is received from the far end as the userid during ppp authentication.
remote:HQ>set bridging onTurns bridging on in the user profile "HQ".
remote:HQ>set timeout 120 Sets the idle timeout parameter to 120 seconds. If there is no interesting traffic to be forwarded across the ISDN connection for 120 seconds then the call will be disconnected. Because the ipx rip updates are periodic by default on the user profile, the call will never disconnect. There are no ipx filters available at this time.
remote:HQ>set 1 number 14085221234Sets the phone numbers in the user profile "HQ" that are used to dial out to the main router. In this case, the main router has the same phone number for both b channels, so the same number is set in link 1 and link 2. Link 2 is for bandwidth on demand. It will not automatically connect if link 1 isn't already connected. Link 2's number is NOT used for a secondary dial number, it is for bandwidth on demand only.
remote:HQ>set 2 number 14085221234Sets the phone numbers in the user profile "HQ" that are used to dial out to the main router. In this case, the main router has the same phone number for both b channels, so the same number is set in link 1 and link 2. Link 2 is for bandwidth on demand. It will not automatically connect if link 1 isn't already connected. Link 2's number is NOT used for a secondary dial number, it is for bandwidth on demand only.
remote:HQ>set 2 number 14085221234Note: In this scenario, the main router is not dialling out to the remote router. If it is necessary for the main router to call out to the remote router, then "set 1 number" and "set 2 number" need to be set in the user profile "remote" with the phone numbers for the remote router.
remote:HQ>set ppp secret host (promts for chap password) Sets the chap secret that will be used to send the chap magic number to the remote router when the remote router challenges the main router.
Enter Password: happyprompted to enter the password/secret. "happy" is entered as the chap secret.
ReEnter Password: happyPrompted to reenter the password/secret to ensure consistency.
remote:HQ>set ppp authentication outgoing chap Sets the ppp authentication on outbound calls to chap. This setting will force bi-directional authentication via chap on the outgoing call basis. When the remote router calls the main router, the remote router will force the main router to authenticate with it via chap.
