Description
This command configures the autonomous system (AS) number for the router. A router can only
belong to one AS. An AS number is a globally unique number with an AS. This number is used to
exchange exterior routing information with neighboring ASs and as an identifier of the AS itself.
If the AS number is changed on a router with an active BGP instance, the new AS number is not used
until the BGP instance is restarted either by administratively disabling/enabling (shutdown/
no shutdown) the BGP instance or rebooting the system with the new configuration.
Default
No autonomous system number is defined.
Parameters autonomous-system — The autonomous system number expressed as a decimal integer.

advertised for this route will be an AS_SET consisting of all elements contained in all paths that
are being summarized.
Use this feature carefully. Aggregating several paths can result in the constant withdrawal and
insertion of AS-PATHs as associated component routes of the aggregate that are experiencing
changes.

form the aggregate route must be entered, followed by the IP address of the BGP system that
created the aggregate route.
