shows an MLP bundle that consists of T1 interfaces from three T3 interfaces.
MLP Bundle for Multilink PPP over Serial Connections
You can combine up to ten T1s to create a Multilink bundle.
The bundle can include T1 channels assigned to different T3s.

A multilink bundle can have up to 10 member links. The router supports both full T1 interfaces and
fractional T1 interfaces as member links, but fractional T1 interfaces are supported only when LFI
is enabled.
You can terminate the serial links on multiple line cards in the router chassis if all of the links
are the same type, such as T1 or E1.
The router supports a maximum of 1250 bundles per system and a maximum of 2500 member links
per system.
The valid multilink interface ranges are from 1 to 9999 (Release 12.2(28)SB and later) and from 1
to 9999 and 65,536 to 2,147,483,647 (Release 12.2(31)SB2 and later). For example:
Router(config)# interface multilink 8
Interleaving is supported on all member links. MLP over Serial-based LFI must be enabled on an
interface that has interleaving turned on.
All member links in an MLP bundle must have the same encapsulation type and bandwidth.
If a virtual template attached to a member link specifies a bandwidth, the router does not clone the
specified bandwidth to the MLP bundle and the member links.
You cannot manually configure the bandwidth on a bundle interface by using the bandwidth
command.
