HP 7000 dl Router manual Both ends must have identical passwords

SROS Command Line Interface Reference Guide PPP Interface Configuration Command Set

Configuring CHAP Example 1: Only the local router requires the peer to authenticate itself.

On the local router (hostname Local):

Local(config-ppp 1)#ppp authentication chap

Local(config-ppp 1)#username Peer password same

On the peer (hostname Peer):

Peer(config-ppp 1)#username Local password same

The first line of this configuration sets the authentication mode to CHAP. This means the peer is required to authenticate itself to the local router via CHAP. The second line is the username and password expected to be sent from the peer. The peer must also have the username up both to verify the incoming username from the local router and to use the password (along with its hostname) in the response to the local router.

Note

Both ends must have identical passwords.

Configuring CHAP Example 2: Both routers require the peer to authenticate itself.

On the local router (hostname Local):

Local(config-ppp 1)#ppp authentication chap

Local(config-ppp 1)#username Peer password same

On the peer (hostname Peer):

Peer(config-ppp 1)#ppp authentication chap

Peer(config-ppp 1)#username Local password same

This is basically identical to Example 1 except that both routers will now challenge each other and respond.

Configuring CHAP Example 3: Using the ppp chap hostname command as an alternate solution.

On the local router (hostname Local):

Local(config-ppp 1)#ppp authentication chap

Local(config-ppp 1)#username Peer password same

Local(config-ppp 1)#ppp chap hostname nearend

On the peer (hostname Peer):

Peer(config-ppp 1)#username nearend password same

Notice the peer is expecting username “nearend” even though the local router's hostname is “Local". Therefore the local router can use the ppp chap hostname command to send the correct name on the challenge.

Configuring CHAP Example 4: Using the ppp chap password command as an alternate solution. On the local router (hostname Local):

Local(config-ppp 1)#ppp authentication chap

Local(config-ppp 1)#username Peer password different

On the peer (hostname Peer):

Peer(config-ppp 1)#username Local password same
