Routing process configuration mode
After route aggregation, the range may exceed the actual network range of the route table, and
sending the data to the nonexistent network may cause loops or increase router loads. To prevent
this situation, the discard-route is added to the route table on the ABR or the ASBR. The
discard-route is generated automatically and will not be transmitted.
The following example disables adding the discard routes generated with the area range command.
Ruijie(config)# router ospf 1
Ruijie(config-router)# no discard-route internal
