MLP on LNS
Networks are migrating from the digital subscriber line (DSL) aggregation network connectivity to
broadband remote access server (BRAS), with the mix of Ethernet and ATM access networks. Therefore,
there is an increasing need to support MLP, and, link fragmentation and interleaving (LFI), to allow
high-priority, low-latency packets to be interleaved between fragments of lower-priority, higher-latency
packets. Voice over IP (VoIP) is an example of a low-latency service.
In the Cisco 12.2(33)SB release, the MLP on LNS feature is introduced for asymmetric digital subscriber
line (ADSL) deployments where the upstream bandwidth (BW) is low. The MLP on LNS feature can
receive fragments from the customer premises equipment (CPE), ensuring that there is less latency
upstream, even if a large packet gets in between the voice packets.
The MLP on LNS feature bundles together a virtual private dial network (VPDN) session on a single
logical connection, which forms an MLP bundle on the LNS. Before the Cisco IOS 12.2(33)SB release,
Cisco 10000 series routers supported only multilink bundle termination on the PPP termination
aggregation (PTA) router. In the Cisco IOS 12.2(33)SB release, Cisco 10000 series routers support MLP
termination on the LNS also.

You cannot apply a virtual template with MLP configured to an MLP bundle.
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.
If link fragmentation and interleaving (LFI) is enabled, only one link is used for interleaving. For
more information, see the "Fragmenting and Interleaving Real-Time and Nonreal-Time Packets"
chapter in the Cisco 10000 Series Router Quality of Service Configuration
We strongly recommend that you use only strict priority queues when configuring Multi-VC MLP
over ATM-based LFI. For more information, see the "Prioritizing Services" chapter in the
Cisco 10000 Series Router Quality of Service Configuration
