ISDN Question

[moses12315]

If i want to use the ISDN BRI all the time and not as a DDR what command shall i use instead of dialer map.....

Secondly ,what shall i do so both BRI are open despite the usage of the WAN

link?

And finally since i use ppp encapsulation do i need to use authentication?

A configuration of the one router is this:

description ………………

bandwidth 128

ip address 10.0.1.69 255.255.255.252

encapsulation ppp

dialer idle-timeout 2147483

dialer map ip 10.0.1.70 name kleio broadcast <phone number>

dialer load-threshold 128 either

dialer-group 1

isdn switch-type basic-net3

no fair-queue

Thanks

Using the dialer map does not have anything to do with whether the BRI is used for DDR or not. The dialer map serves to indicate how the BRI should connect: what number to dial, what IP address to expect, perhaps what the remote name is and perhaps whether to enable forwarding of broadcast/multicast. The alternative to dialer map is the dialer string if you want to only indicate what number to dial.

If you want both channels you can define a load threshold.

You are enabling the BRI to dial out and potentially to receive calls. If you want to connect and not know who you have connected to then you do not need ppp authentication (typically you do not want ppp authentication when it is a leased line with ppp). For I dial connection I would surely want to authenticate. But the decision is up to you.

If you want the BRI to come up and stay up you probably want a very broad definition of interesting traffic in the dialer group and dialer list. And you probably want to configure a very long inactivity timeout.
