Is it possible to combine 3 Bri Interfaces (6 Channels) to come up at the same time when the primary link goes down. I know 2 Bri Channels on Bri interface can be combined through Multilink PPP, but has never done to combine 3 physical Bri ports as a one link.
Is it possible?
2) What is the best way to bring the ISDN up for static routes. I guess I have no choice except creating static routes with the higher adminstrative distance.
I am talking about atleast monitoring 15 to 20 static routes. Do I have anyother choices.
This should be possible. Multilink PPP should even work over links on different routers. This is not an easy config to build, but in the configuration guide you should find what you are looking for under multilink PPP.
2: To my best knowledge, floating static routes are indeed the best solution for this situation.
Ideally, you should arrange for a group-number. That is: all three bri's answer the same DN.
It is not so that a particular DN is attached to a fixed B-channel. The DN's are meant to make it possible that multiple devices can be attaced to one ISDN line without interfering with eachother. Each device only answers calls to his assigned DN.
With Cisco, use the isdn answer command to use this feature.
