Virtual-template interface and multilink PPP

Lets say I have a physical link between 2 routers running Frame-Relay. I
have three DLCIs on each side that

point to the other end. I want to combine the three DLCIs on each side under
one interface & subnet so I decide

to use a virtual-template with multilink PPP.

Question: Am I required to configure a multilink interface and configure the
virtual-template interface as a member

of its multilink group or can I just configure multilink-ppp under
the virtual-template
interface??

So if I have this:

R1:

serial 0/0

encapsulation frame-relay

frame-relay interface-dlci 102 ppp virtual-template 1

frame-relay interface-dlci 112 ppp virtual-template 1

frame-relay interface-dlci 122 ppp virtual-template 1

R2:

serial 0/0

encapsulation frame-relay

frame-relay interface-dlci 201 ppp virtual-template 1

frame-relay interface-dlci 211 ppp virtual-template 1

frame-relay interface-dlci 221 ppp virtual-template 1

On R1 do I need this:

multilink 1

ip address 1.1.1.1 255.255.255.0

encapsulation ppp

ppp multilink-group 1

virtual-template 1

ppp multilink

ppp multilink-group 1

Or can I just go with this:

virtual-template 1

ip address 1.1.1.1 255.255.255.0

ppp multilink

Thanks,

Bryan R.
