    Configuring Link Bundling This module describes the configuration of link bundle interfaces on the Cisco NCS 6000 Series Router. A link bundle is a group of one or more ports that are aggregated together and treated as a single link. The Link Bundling feature allows you to group multiple point-to-point links together into one logical link and provide higher bidirectional bandwidth, redundancy, and load balancing between two routers.
