with PPP
Hirschmann routers also support the point-to-point protocol (PPP). PPP is a
generic term for a whole series of WAN protocols which enable the interac-
tion of routers made by different manufacturers since this protocol is support-
ed by practically all manufacturers.
Due to the increasing importance of this protocol family and the fact that PPP
is not associated with any specific operating mode of the routers, we will be
introducing the functions of the devices associated with the PPP here in a
separate section.
11.10.1The protocol
U What is PPP?
The point-to-point protocol was developed specifically for network connec-
tions via serial channels and has asserted itself as the standard for connec-
tions between routers. It implements the following functions:
D Password protection according to PAP, CHAP or MS CHAP
D Callback functions
D Negotiation of the network protocol to be used over the connection estab-
lished (IP or IPX, for example). Included in this are any parameters nec-
essary for these protocols, for example IP addresses. This process is
carried out using IPCP (IP Control Protocol).
