RouterA(conf)#int multilink 3
and configured..
But in my router having only this option
RouterB(conf)#multilink bundle-name authenticated

Multiclass multilink PPP provides the ability to fragment packets of various priorities into multiple classes, allowing high-priority packets to be sent between fragments of lower priorities. In multiclass multilink PPP, outgoing packets can be divided into four different multilink classes. Each class has its own governing sequence number, and the receiving network peer (bundle) sorts and processes each class independently. Sequence numbers are embedded in the multilink header and used internally to reassemble packets.
Multiclass multilink PPP must be successfully negotiated with the peer system. If multiclass multilink PPP cannot be negotiated with the peer system, the router uses standard interleaving, Priority queue traffic is always PPP encapsulated when interleaving with non-priority traffic.
STEPS
1. enable
2. configure terminal
3. interface multilink multilink-bundle-number
4. ip address ip_address mask
5. ppp multilink
6. ppp multilink interleave
7. ppp multilink fragment delay milliseconds [microseconds]
8. ppp timeout multilink lost-fragment seconds [milliseconds]
9. ppp multilink multiclass local {request [initial init-value] [maximum max-value] | allow [maximum max-value] | forbid}
10. ppp multilink multiclass remote {apply [minimum min-value] | reject | ignore}
11. no cdp enable
12. exit

the requirement of multilink is for aggregation of bandwidth. Logically it is called a bundled bandwidth. It means if you have 2 e1's then you can club the 2 e1 and get a single logical 4mb bandwitdth pipe. With this you will get the redundancy also, if any of the link goes down, capacity of link will down to 2 mb.
How to configure:-
first go to the serial interface and choose the encapsulation type ppp.
int serial 0/0
encapsulation ppp
ppp multilink group 1
end
int multilink 1
ip address x.x.x.x/30
how to check ppp
show ip multilink interface multilink 1

multilink bundle-name authenticated is used for authentication.
