Link Bundling Overview
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 one 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.
