6.7.2 Configuring OSPFv3 Route Aggregation

An ABR can summarize routes with the same prefix into one LSA and advertise the summarized
route in other areas. An ASBR can also summarize imported routes with the same prefix into
one LSA and then advertise the summarized route to other areas. This can reduce the size of the
LSDB in other areas.
Context
If multiple continuous network segments exist in this area, use the abr-summary command to
summarize them into one network segment. In this way, the ABR only sends an LSA after
summarization. No LSA that belongs to the summarization network segment is separately
transmitted, therefore reducing the LSDB size of other areas.
When a large number of routes are imported, use the asbr-summary command to summarize
the imported routes and set the delay for advertising the summarized route. In this manner, the
summarized route advertised each time contains more valid routing information, and network
flapping caused by incorrect routing information is avoided.
