its own IP interface. In addition to these PPPoE sessions, pure IP traffic can run concurrently over the same Ethernet port. This is achieved by binding the Ethernet port directly to an IP interface.

PPP configuration task list

To configure PPP, perform the following tasks:

Creating an IP interface for PPP

Configuring for IP address auto-configuration from PPP (see page 317)

Creating a PPP subscriber (for authentication) (see page 317)

Configuring a PPPoE session (see page 319)

Configuring PPP over a HDLC Link

Creating a PPP interface within the CS context (not currently available)

Creating a PSTN interface for PPP dial-in/dial-out (not currently available)

Creating a PPP profile (see page 321)

Displaying PPP configuration information (see page 324)

Debugging PPP (see page 325)

Creating an IP interface for PPP

An IP interface is required to link a PPP connection to the IP context. The IP interface must apply a network address port translation (NAPT) if the PPP service provider only offers a single IP address and not an IP sub- net, or if the IP addresses on the LAN shall be private and hidden behind a public IP address (see 11, “NAT/ NAPT configuration” on page 132 for more information about NAPT).

This procedure describes how to create an IP interface for PPP

Mode: Context IP

Step

Command

Purpose

 

 

 

1

node(ctx-ip)[router]#interface name

Creates the new interface name, which repre-

 

 

sents an IP interface.

 

 

 

2

node(if-ip)[name]#point-to-point

Only defines what route is entered into the IP

 

 

routing table:

 

 

point-to-point: A route to the IP address of

 

 

the PPP interface (assigned by the PPP peer)

 

 

is entered into the routing table.

 

 

no point-to-point: A route to the subnet

 

 

defined by IP address of the PPP interface

 

 

(assigned by the PPP peer) is entered into

 

 

the routing table. The class of the IP address

 

 

determines the size of the subset.

 

 

Recommendation: Use ‘point-to-point’ and spec-

 

 

ify a default route.
