Note:
When configuring CHAP authentication, you should configure the same username with
the local-user command executed as that with the ppp chap user command executed
for the peer. You should also configure the same password for both sides. If the peer
does not use the local-user command to configure the local user, the peer
encapsulates the received authentication request from all PPP users using the key (the
key is configured by the ppp chap password command) and responds to the local user.

1.2.4 Configuring PPP Negotiation Parameters

The following PPP negotiation parameters can be configured:
Time interval between negotiation timeout. During PPP negotiation, if the response
message of the peer is not received within this time interval, PPP will retransmit the
message. The timeout interval ranges from 1 to 10 seconds.
For some negotiation parameters of NCP such as the configuration of local IP address
and the IP address assigned to the peer, refer to the "Network Protocol Configuration"
part in this manual. For example, the ip address ppp-negotiate command can be
used to ask the peer to assign IP address for the local, while the remote address
command can be used to designate the local to assign IP address for the peer.
Perform the following configuration in interface view.
I. Configuring the time interval of PPP negotiation timeout

II. Negotiating IP address using PPP
1) Configure client
Suppose PPP has been encapsulated on local and remote interfaces. If the local
interface has no IP address while the remote interface has one, you may configure the
local interface to allow it to negotiate an IP address using PPP and accept the IP
