Dial on demand cisco 801

[Deleco]

Hi

I am setting up a WAN with cisco 801 routers. The problem is the routers connect to each other as soon as they are both turned on (I assume this as the ch1 light is on). What i need to happen is that the routers only dial on demand, for instance when a drive is mapped. Or i would also be happy if the routers only communicated with each other at certain times. But the first would be preferable.

Any help would be greatly appreciated.

Regards

You need to search on

http://www.cisco.com

for ddr. You will find dozens of white papers and examples. Then you need to reference you 801 documentation or look that up on CCO too. It doesn't use the standard IOS that we all know and love.

The Cisco 800 Series use the same IOS as the 2500's and such.

You need to define what traffic is interesting to the router, so that when the router receives a packet that is defined as interesting it calls the other router to initiate a connection.

I would attach a sniffer and then map a network drive to see the traffic caused the the PC trying to map the drive. If you use LMHOSTS localy then (so the pc will not send a wins call to get an IP address of the UNC you entered) the pc will send a packet to the IP address of the server you want to map a drive off. example.

LMHOST entery
NT server name CORP
ip address 192.168.0.1

On the router create an access-list (global command:

access-list 101 ip permit any host 192.168.0.1

Creat a dialer list (global command):

dialer-list 1 list 101

On the interface or Dialer-Profile:

Dialer-group 1

This should cause the router initiate an connection when a PC is trying to map a drive if you have LMHOSTS localy or a local WINs server on that subnet. Also make sure that your dialer map statement does not have the BROADCAST keyword, this will then allow the connection to forward broadcast (not good) just unicast traffic should be forwarded from a remote site over any dialup wan link.
