In theory, allows you to build one logical link that has the combined bandwidth of the bounded physical links. So, dual T-1s would perform much like a single 3 Mbps link. (Similar concept as EthernetChannels.)

Sorry for the response delay, was out of town for the last 3 days.


Not exactly sure what "advantages" you want to see a link for. You might look at:

http://www.cisco.com/en/US/docs/ios/11_3/dial/configuration/guide/dcppp.html#wp6036

or

http://www.cisco.com/en/US/docs/ios/11_2/wan/configuration/guide/4cppp.html

and see if the informtion about multilink is what you're looking for.


PS:

You can find much more searching both the Cisco web site and/or the Internet.

For Multilink PPP (aka MLPPP aka MPPP aka MLP)

1. You can use LFI. That is you can fragment and interleave packets.


2. You can bundle links in a way you desire.


3. Logical management - one spot for all the config.
