Ppp Authentication - HP ProCurve Secure 7000dl Series Basic Management And Configuration Manual

N o t e
Configuring the Data Link Layer Protocol for E1, T1, and Serial Interfaces
Replace <physical interface> with the type of WAN connection, such as E1,
T1, or serial. Replace <slot> and <port> with the correct numbers to identify
this interface's location on the ProCurve Secure Router.
If you are binding an E1 or T1 interface to the PPP interface, replace <TDM-
group number> with the TDM group number you created on the E1 or T1
interface. If you are binding a serial interface to the PPP interface, omit this
option.
You do not include a TDM group number when binding a serial interface to a
logical interface because the serial interface does not use TDM groups.
Replace <logical interface> with ppp and replace < logical interface num-
ber> with the number you assigned to this interface. For example, if you want
to bind the E1 1/1 interface or the T1 1/1 interface to the PPP 1 interface, enter:
ProCurve(config)# bind 1 e1 1/1 1 ppp 1
or
ProCurve(config)# bind 1 t1 1/1 1 ppp 1
If you want to bind the serial 1/1 interface to the PPP 1 interface, enter:
ProCurve(config)# bind 1 ser 1/1 ppp 1
To see an example configuration that uses PPP, see "Example Networks" on
page 6-46.

PPP Authentication

You can increase the security of your WAN by requiring the PPP peer at the
other end of the link to vouch that it is, indeed, the authorized router at the
remote site. You can also configure the router to provide its own authentica-
tion information. Many Internet service providers (ISPs) require authentica-
tion so that they grant service only to subscribers who have paid for it.
The ProCurve Secure Router supports two authentication protocols for PPP:
PAP
CHAP
PAP. PAP is the simplest possible authentication scheme. It requires a two-
way message exchange. One peer sends the password previously agreed upon
to the other peer, which is called the authenticator. The authenticator looks
up the password in its database. If the password matches, the authenticator
