Command Reference OSPFv2 Commands
Sets the tag value of an aggregate route. The range is from 0 to
4,294,967,295.
Cost value of the aggregate route. The range is from 0 to 16,777,214.
No aggregate route is configured by default.
Routing process configuration mode
When routes are redistributed by another routing process into the OSPF routing process, every route
is advertised to the OSPF-enabled device separately in external LSAs. If the incoming routes are
continuous addresses, the autonomous border device can advertise only one aggregate route,
reducing the scale of routing table greatly.
Unlike the area range command, the area range command aggregates inter-OSPF-area routes,
while the summary-address command aggregates external routes of the OSPF routing domain.
For the NSSA, the summary-address command is valid only on the NSSA ABR now, and
aggregates only redistributed routes.
The following example generates an external aggregate route 100.100.0.0/16.
Ruijie(config)# router ospf20
Ruijie(config-router)# summary-address100.100.0.0 255.255.0.0
Ruijie(config-router)# redistribute static subnets
Ruijie(config-router)# network200.2.2.0 0.0.0.255 area 1
Ruijie(config-router)# network172.16.24.0 0.0.0.255area 0
Ruijie(config-router)# area1nssa
Configures route convergence on the OSPF
area border device.
Redistributes routes of other routing processes.
Use this command to configure the time delay for the same LSA received. Use the no form of this
command to restore the default setting.
