Now I will do small Lab:
The Goal is that create a PPP Multilink on R1 and R2 so that the link between them will be double speed with IP address as follow:

R1:  /30
R2: /30Step 1) go to each router and give the PPP encapsulation

R1#show ip int brief

Interface IP-Address OK? Method Status Protocol
FastEthernet0/0 unassigned YES Method administratively down down
Serial1/0 unassigned YES manual up up
Serial1/1 unassigned YES Method up up
Serial1/2 unassigned YES Method administratively down down
Serial1/3 unassigned YES Method administratively down down
Loopback1 YES manual up up

R1#config t

Enter configuration commands, one per line.  End with CNTL/Z.

R1(config)#int s1/0

R1(config-if)#encapsulation ?

atm-dxi         ATM-DXI encapsulation

bstun           Block Serial tunneling (BSTUN)

ppp             Point-to-Point protocol

sdlc            SDLC

    thank you putting togather the multilink video.
    I was following the note to exercise the multilink ppp. However I couldn’t get the multilink option under global config. I am not sure what I missed. please see the result of the configuration.

    Dear Mesele;

    Thank you for your comments ; in order to see above commands you need to use real router or GNS3 ; this will not work on Packet Tracer. Thank you
