We are trying to establish a 6 channel multilink connection using 3 ISDN lines. We are able to connect with 2 channels and get a 128K connection, but after we try to bring up the third channel, the connection becomes unuseable and soon disconnects. We are using a cisco router with 3 BRI interfaces, and have been working with Cisco to build a config that makes this work. They say it is possible and should work with our current config. My quetion is, has anyone else been able to do something like this? The most channels we have ever bonded has been 2, so I am not sure if there is something I am missing. Radius is authenticating the user just fine, so I don't believe it is a cause of the problem. Is this something that can be done? If so, are there any special configuration options I should be looking at?
