Hello,
I just finished setting up a bundle of (2) T1's in a multilink bundle and I'm having issues with one of the T1's not wanting to join the bundle.
The router I'm using on the remote office location is a 3620 router running code c3620-i-mz.121-1c.bin
The campus router which is a 7206 is setup the same exact way with multilink 240 and like I've said, serial 0/0 is joined to the bundle just fine, so we are running off one T1 connection.
The serial interface that is not working is: serial 0/1
Can you please help? Thanks

Hi,
can you do sh controllers s0/0 and sh controllers s0/1
Alain.
11-03-2011 01:19 PM
Thanks for the reply, after moving S0/1 off the multilink group and setting as a point-to-point again, the interface came up.
If I move it back to the multilink group, it will go down again.
Here is the output you are requesting:
