Description
Prevent different routing devices within an AS from creating aggregate routes that contain different AS paths.
Junos OS performs route aggregation, which is the process of
combining the characteristics of different routes so that only a single
route is advertised. Aggregation reduces the amount of information
that BGP must store and exchange with other BGP systems. When aggregation
occurs, the local routing device adds the local AS number and the
router ID to the aggregator path attiribute. The no-aggregator-id
statement causes Junos OS to place a 0 in the router ID field and
thus eliminate the possibility of having multiple aggregate advertisements
in the network, each with different path information.
Default
If you omit this statement, the router ID is included in the BGP aggregator path attribute.
