To require CHAP authentication from the peer:
1. Move to the configuration mode for the backup PPP interface.
2. Enable CHAP authentication:
ProCurve(config-ppp 2)# ppp authentication chap
3. Add the peer router's hostname and password to the PPP database:
ProCurve(config-ppp 2)# username LondonRouter password procurve
Providing Authentication to the Peer. If the remote router's backup
interface requires authentication, you must configure the backup interface
with the correct authentication information.
To configure a PAP username and password:
1. Move to the configuration mode for the backup PPP interface.
2. Enter the username and password you have received from your peer:
Syntax: ppp pap sent-username <username> password <password>
If you are backing up a connection to an ISP, the username and password
will probably be the same as those you received for the primary connec-
tion. For example, enter:
ProCurve(config-ppp 2)# ppp pap sent-username NewYork password procurve
To configure a CHAP username and password:
1. Move to the configuration mode for the backup PPP interface.
2. Enter the password you have received from your peer:
Syntax: ppp chap password <password>
If you are backing up a connection to an ISP, this will probably be the same
password that you received for the primary connection. For example,
enter:
ProCurve(config-ppp 2)# ppp chap password procurve
3. The router automatically sends its hostname. If your peer has assigned
you a different username than your hostname, enter:
Syntax: ppp chap hostname <username>
