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.
