Using ISDN PRI for dial back up

[kgrunduski]

Has anybody had any experience using ISDN PRI for high speed dial back up ? I'd like to see sample configs if possible.

Thanks

Yes, works like a charm. Here are several links with samples depending on specifics of your configuration should help you on your way.

I actually am looking to do MLPP and go from PRI to PRI not BRI to PRI. Any experience there ?

Here is a couple with MLPPP... Hope this is what you're looking for.

PRI to PRI works fine using MLPPP. I prefer to limit the MLPPP bundle to a single PRI (24 or 30 channels). If you need more, there is a hack to force DDR over multiple PRIs illustrated in my book (see listings 5-6 and 5-7 on my web site) , but the addressing limitations are pretty severe and it depends upon bugs in Cisco's RIP implementation to generate the required forcing traffic.

Good luck and have fun!
