PPP Multilink Interleave Is Not Working

Hi Everybody,

 

I have configured PPP multilink between r1 and r2 using one serial interface on each router. Everything is working fine except that interleaving seemed to be disabled in the output of the "show ppp multilink" command. I have included all the necessary show commands to help you help me figure out why interleaving is not working.

 

Note: To help you run through this quickly, I have highlighted some text with bold red color.

 

Thank you for any help.

 

r1#show ppp multilink
