DETAILED STEPS
Command Purpose
Step 1
interface dialer dialer-rotary-group-number
Example:
Router(config)# interface dialer 0
Router(config-if)#
Creates a dialer interface (numbered 0 to 255) and
enters interface configuration mode.
Step 2
ip address negotiated
Example:
Router(config-if)# ip address negotiated
Router(config-if)#
Specifies that the IP address for the interface is
obtained through PPP/IPCP (IP Control Protocol)
address negotiation.
Step 3
ip mtu bytes
Example:
Router(config-if)# ip mtu 1492
Router(config-if)#
Sets the size of the IP maximum transmission unit
(MTU). The default minimum is 128
bytes. The
maximum for Ethernet is 1492
bytes.
Step 4
encapsulation encapsulation-type
Example:
Router(config-if)# encapsulation ppp
Router(config-if)#
Sets the encapsulation type to PPP for the data
packets being transmitted and received.
Step 5
ppp authentication {protocol1
[protocol2...]}
Example:
Router(config-if)# ppp authentication chap
Router(config-if)#
Sets the PPP authentication method to Challenge
Handshake Authentication Protocol (CHAP).
