Step 11
ip route prefix mask {ip-address | interface-type
interface-number [ip-address]}
Example:
Router(config)# ip route 0.0.0.0 0.0.0.0 22.0.0.2
Router(config)#
Sets the IP route to point to the dialer
interface as a default gateway.
Step 12
access-list access-list-number {deny | permit} source
[source-wildcard]
Example:
Router(config)# access-list 1 permit 192.168.0.0
0.0.255.255 any
Defines an extended access list that
indicates which addresses need
translation.
Step 13
dialerwatch-list group-number {ip ip-address
address-mask | delay route-check initial seconds}
Example:
Router(config)# dialer watch-list 1 ip 22.0.0.2
255.255.255.255
Router(config)#
Evaluates the status of the primary link,
based on the existence of routes to the
peer. The address 22.0.0.2 is the peer IP
address of the ISP.
Step 14
line [aux | console | tty | vty] line-number
[ending-line-number]
Example:
Router(config)# line console 0
Router(config-line)#
Enters configuration mode for the line
interface.
Step 15
modem enable
Example:
Router(config-line)# modem enable
Router(config-line)#
Switches the port from console port to
auxiliary port function.
Step 16
exit
Example:
Router(config-line)# exit
Router(config)#
Exits interface configuration mode.
