Configuring WAN interfaces
Use the command ip unnumbered <interface>, where <interface> is the name of
another interface in the media gateway (for example, the WAN interface) from which an IP
address for the dialer interface is borrowed.
Use this command when you don't know who will eventually be your peer and you
●
want to run dynamic routing protocols (for example, OSPF or RIP) over the dialup link.
G350-001(if:dialer 1)# ip address 4.5.6.7 255.255.255.0
Done!
5. Use the dialer persistent initial delay command, with the value 30 seconds,
to prevent dialup after boot, before the WAN link is fully functional.
G350-001(if:dialer 1)# dialer persistant initial delay 30
Done!
6. Use the dialer persistent max-attempts command to set the maximum number
of Dialer attempts.
G350-001(if:dialer 1)# dialer persistent max-attempts 10
Done!
The Dialer interface dials each number associated with a dialer string, in order, until either
a connection is made, or the number configured in the dialer persistent
max-attempts command is reached.
7. Configure an authentication method and parameters (if required):
- For PAP authenticating, type the ppp pap-sent command, followed by a username
and password. For example:
G350-001(if:dialer 1)# ppp pap-sent username avaya32 password 123456
Done!
- For CHAP authentication, use the ppp chap hostname command, followed by a
hostname, and the ppp chap password command, followed by a password. For
example:
G350-001(if:dialer 1)# ppp chap hostname avaya32
Done!
G350-001(if:dialer 1)# ppp chap password 123456
Done!
Note:
Authentication parameters do not appear in the startup or running configuration
Note:
files. You can use the show ppp authentication command to view
authentication status. The copy running-config startup-config
command stores authentication parameters in NVRAM.
