Values mask
The mask associated with the network address expressed as a mask length.
Values 0 — 32
summary-only — This optional parameter suppresses advertisement of more specific component
routes for the aggregate.
To remove the summary-only option, enter the same aggregate command without the
summary-only parameter.
as-set — This optional parameter is only applicable to BGP and creates an aggregate where the path
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.
aggregator as-number:ip-address — This optional parameter specifies the BGP aggregator path
attribute to the aggregate route. When configuring the aggregator, a two-octet AS number used to
form the aggregate route must be entered, followed by the IP address of the BGP system that
created the aggregate route.
autonomous-system
Syntax autonomous-system as-number
no autonomous-system
Context config>router
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 as-number — The autonomous system number expressed as a decimal integer.
Values 1 - 65535
