Configuring PPP negotiation
Introduction to PPP negotiation parameters
PPP negotiation parameters that can be configured include, negotiation timeout time, IP address
negotiation, and DNS server address negotiation.
• Negotiation timeout time
Negotiation timeout time determines the interval for sending request packets. During PPP
negotiation, if no response is received from the peer during a specific period after the local device
sends a packet, the device sends the packet again. The period is known as negotiation timeout
time, which ranges from 1 to 10 seconds.
• IP address negotiation
IP address negotiation can be implemented in the following two modes.
{
The device operating as the client: You can configure the local interface to operate in this mode
if it uses PPP at the data link layer but does not have an IP address, whereas the peer is
configured with an IP address, after which the interface can receive an IP address allocated by
its peer. This configuration applies to the situations where you access the Internet through ISP.
{
The device operating as the server: In this case, you must configure a local IP address pool in
domain view or system view to specify the range of the IP addresses to be allocated, and then
bind the address pool to the interface.
• DNS address negotiation
PPP address negotiation can also determine the DNS server address. You can configure a device
to allocate the DNS server address to the peer or receive the DNS server address from the peer.
Normally, for a PPP link between a PC and a device, the DNS server address is usually allocated
by the device, through which the PC can access the Internet directly using domain names. For a
PPP link established between a device and the access server of a carrier, the DNS server address
is usually allocated by the access server, through which the device can resolve domain names
through the DNS server address allocated by the access server.
