Have a look at this link, I wrote this a while back and pretty much answers your question.

Hi GS,
currently I configure multilink ppp over serial interface.
Now I'm confused about a behavior ..
Assume first I configure the serial link s0/0 with encaps ppp. This interface has also an ip address assigned.
Then I configure a routing protocol over this line...all works fine.
After that I should configure ppp multink over this interfaces.
1. What is the correct order of configuring this ? Should I at first configure the multilink interface and than attach to the serial IF ?
Or should I first configure the association on the serial interface an then create the multilink interface ?
2. What about the IP addresses ? I found out after configuring the multilink interface the routing neighors are between the multilink interface although the same ip address is on both interfaces ( serial and multilink)
Therefore should I remove the ip address from the serial link ?? Is the multilink interface the part for all layer 3 configuratins ?
