Example: Configuring a Multilink Interface (NSM Procedure)
On available devices, you can configure and access multiple serial links called a bundle, through a virtual interface called a multilink interface. The multilink interface emulates a physical interface for the transport of frames.
In this example, you combine two WAN subinterfaces into an multilink interface. The name of the multilink interface must be mlid_num. For example, multilink interface names can be ml1, ml2, and so on.
