Create an SD-WAN link tag to group paths going to the
same destination.
Create a link tag to identify one or more
physical links that you want applications and services to use in
a specific order during SD-WAN traffic distribution and failover protection.
Grouping multiple physical links allows you to maximize the application
and service quality if the physical link health deteriorates.
When
planning how to group your links, consider the use or purpose of
the links and group them accordingly. For example, if you are configuring
links intended for low-cost or non-business-critical traffic, create
a link tag and group these interfaces together to ensure that the
intended traffic flows primarily on these links, and not on more
expensive links that may impact business-critical applications or
services.
