Question:
When you deploy multilink PPP on your network, where must you configure the group IP Address on each device?

In the global config
Under serial interface
Under the routing protocol
Under the multilink interface

Explanation: Suppose R1 has two Serial interfaces which are directly connected to R2. This is how to configure multilink on R1:

R1(config-if)# interface Serial 0/0 
R1(config-if)# encapsulation ppp 
R1(config-if)# ppp multilink 
R1(config-if)# ppp multilink group 1 
R1(config-if)# no shutdown

R1(config-if)# interface Serial 0/1 
R1(config-if)# encapsulation ppp 
R1(config-if)# ppp multilink 
R1(config-if)# ppp multilink group 1 
R1(config-if)# no shutdown

R1(config)# interface multilink 1 
R1(config-if)# ip address 192.168.42.1 255.255.255.252 
R1(config-if)# ppp multilink 
R1(config-if)# ppp multilink group 1

Therefore we must configure IP address under multilink interface, not physical member interfaces.
