6.30.4 Configuring Route Aggregation
Use the aggregate-address command to configure an aggregated route in the
route configuration mode. Once any route is within the configured range, this
aggregated route will take into effect.
The concrete configuration is shown as follows:
router bgp 100
aggregate-address 193.0.0.0 255.0.0.0
Configure one aggregate route:
router bgp 100
aggregate-address 193.0.0.0 255.0.0.0 as-set
The as-path segment of the aggregated route is an collection of ASs:
router bgp 100
aggregate-address 193.0.0.0 255.0.0.0 summary-only
The aggregated route will not be advertised
