the traffic on a different link. If this attempt also fails, the router uses a round-robin
approach.
You can configure bundles as follows:
On a cOCx/STMx line module and its corresponding I/O modules, you can configure:
Member links from different OC3/STM1 ports in the same bundle
The 336 available T1 channels combined in any manner that does not exceed 8 links
per bundle (for example, 336 single-link T1 bundles, 42 eight-link bundles, or 41
eight-link bundles and 8 single-link bundles)
The 252 available E1 channels combined in any manner that does not exceed 8 links
per bundle (for example, 252 single-link E1 bundles, 34 eight-link bundles, or 33
eight-link bundles and 8 single-link bundles)
On a COCX-F3 line module and its corresponding I/O modules, you can configure:
Up to 8 member links from different ports in the same bundle
Up to 12 bundles
On a CT3 or CT3/T3-F0 line module and its corresponding I/O module, you can
configure:
Only member links from the same T3 interfaces into the same bundle. You cannot
configure member links from different T3 ports in the same bundle.
The 28 available T1 channels on each port combined in any manner that does not
exceed 8 links per bundle (for example, 28 single-link T1 bundles or 3 eight-link
bundles and 4 single-link bundles per port)
E Series routers do not support the following MLFR features:
Fragmentation
The router does not support MLFR fragmentation or reassembly. When using MLFR
on the router, configure all peer devices so that they do not fragment MLFR frames.
The router drops all fragmented frames that it receives.
Resequencing of out-of-order packets in the absence of fragmentation
Given the location in the network where the router resides, the NxT1 links to a customer
site represent one of many places across the IP network where packets might be
received out of order. For example, if the router has multiple uplinks to a core router,
packets might be received out of order across these links. Packet resequencing is
therefore left as an exercise for the end station rather than the aggregation router.
