Dynamic AS Number Notation Application
Dell Networking OS applies the ASN notation type change dynamically to the running-config statements.
When you apply or change an asnotation, the type selected is reflected immediately in the running-configuration and the show
commands (refer to the following two examples).
Example of Dynamic Changes in the Running Configuration When Using the bgp asnotation Command
