Prerequisites For Configuring Link Bundling - Cisco 6000 Series Configuration Manual

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. A virtual
interface is assigned to the bundled link. The component links can be dynamically added and deleted from
the virtual interface. The virtual interface is treated as a single interface on which you can configure an IP
address and other software features used by the link bundle. Packets sent to the link bundle are forwarded to
one of the links in the bundle.
Each bundle has a single MAC and shares a single Layer 3 configuration set, such as IP address, ACL, Quality
of Service (QoS), and so on.
Note Link bundles do not have a one-to-one modular services card association. Member links can terminate on
different cards.
