isdn config

when setting up isdn, if I just wanted to get 1 ip range say a 10.0.0.0 network to trigger the line, would I just create an access list like this

access-list 100 permit 10.0.0.0 0.255.255.255

then do dialler list 1 protocol ip list 100

is this right ?

would I need to put an in/out statement on anywhere or not ?

thanks for your help !!

Re: isdn config

Hello Carl,

a standard access list would indeed be sufficient to trigger the ISDN:

access-list 1 permit 10.0.0.0 0.255.255.255

dialer-list 1 protocol ip list 1

In your example you are using an extended access list (100), which requires a source and destination. If you want to use that, the configuration would look like this:

access-list 100 permit ip 10.0.0.0 0.255.255.255 any

dialer-list 1 protocol ip list 100

The effect is the same: outbound traffic from the 10.0.0.0/8 range will trigger the ISDN line...

HTH,

GP
