Unable to get Multi-link bundles to come up.

I have a 2 routers with 2 p2p T1s connected. I have been trying to apply the ppp multilinks to the T1 interfaces. I can get the multilinks applied but only one P2p is showing up int the int mu.

Here are the configurations.

I do not see any issues in the config part that you posted. Can you post the output of show interface from each of the routers?

If you take the T1s out of the multilink what does the serial interface look like then? I am doubtful that there is a multilink problem and suspect that you have some problem on that serial link.

Re: Unable to get Multi-link bundles to come up.

Please include the configuation on the multilink interface. The output should be something like:

interface Multilink4

ip address xxx.xxx.xxx....

ppp multilink

ppp multilink group 4

Re: Unable to get Multi-link bundles to come up.

Just dropping in as third.

How about debugging what is happening on the links?

The output of the following will tell us a lot more:

debug ppp neg

debug ppp multilink

Leo
