Cisco PRI configuration question

[sleepygordon]

Hi!

While trying to replace a E1 with an ISDN PRI, do I need to configure DDR? Can i just route the traffic to the serialx/y:15?

You don't have to configure DDR to use ISDN if you want. It will mean however that a call will be raised whenever any traffic hits it that requires routing, i.e. there is no interesting traffic definition and ALL traffic can generate a call.

Rather than route your traffic to the ISDN D Channel, you should allocate your ISDN interface to a dialer pool and then create a dialer interface and assign this to that pool, as below:


interface sx/y:15
dialer pool-member 1

interface Dialer0
dialer pool 1

ip route 0.0.0.0 0.0.0.0 dialer0
