Questions:

1. Can I have the dialer2 dial to diffrent phone no and diffrent subnet using "dialer map" (So I have other RAS server located to backup site-192.168.12.0)

2. If so, the ip route 192.168.12.0 255.255.255.0 192.168.251.5 201; will the command be interesting to place the second call?


So, my setup will Frame-relay, ISDN, DIAL #1, DIAL #2


Thank's in Advanced,


Best Regards,

HATO

Q1. Can I have the dialer2 dial to diffrent phone no and diffrent subnet using "dialer map" (So I have other RAS server located to backup site-192.168.12.0)


A1. Yes, but... You also will need a mechanism that will detect when the alternate dialer is required. This is not supported by standard Cisco configurations, but can be done with a little trickery.


Q2. If so, the ip route 192.168.12.0 255.255.255.0 192.168.251.5 201; will the command be interesting to place the second call?


A2. No. As far as the 2nd dialer is concerned, the first dialer is always available (it will either be up or up(spoofing)).


Q3. So, my setup will Frame-relay, ISDN, DIAL #1, DIAL #2


A3. You can do this, but you'll need to start over using either dialer watch or BGP driven DDR to do the job. This also requires using an easily filtered routing protocol such as EIGRP or RIPv2 between the two sites so the calling router can detect which links are up and available.


See the white paper "Using BGP to Trigger Multiple Levels of Dial Backup on Cisco Routers" on my web site (or Chapter 5 - "Advanced Dial Backup" of my book High Availability Networking with Cisco) for more on the techniques required to do the job.


Good luck and have fun!
