Hello,
I'm configuring the PPP Multilink of 3 E1 channel in Cisco router(75xx, 72xx). I search there and I found few methods to confiugre multilink. May I ask what is the different between these methods?
1. Multilink group
2. virtual-template
3. Dialer group
This is my understanding of different between these three methods:
- Only one multilink channel is allowed in Virtual-template method;
- Dialer group is the old method, for ISDN interface;
- Multilink group is the new method only sync/serial interface.
BTW, Which is most suitable for my case?
Thank you very much.

Here is the url for sample config on how to bundle dedicated lines using "multilink group" for your ref.

Most effective method will be using "virtual-template". You can ad sam many channels in the bundle using "ppp multilink" under "interface virtual-template x" and under physical interface. So there is no restriction of just one channel is allowed using Virtual-template.
Dialer-group is really old method..i agree..
Now multilink-group is used when you want to multilink or bundle more then one "Leased" line or "dedicated" Line (which is not channelized).
So whenever you want to bundle/multilink more then one b channels of channelized T1/E1 line, use "virtual-template". Also you need to use that when you have some per user bases authorization attributes to be downloaded from AAA to router.

Hello,
Thanks a lot! I got clear now. Finally we would apply the Multilink group method because threre are three "dedicated" E1 link (three physical line).
