by OSPF.
Use the undo asbr-summary command to cancel the summarization.
By default, summarization of imported routes is disabled.
After the summarization of imported routes is configured, if the local router is an
autonomous system border router (ASBR), this command summarizes the
imported Type-5 LSAs in the summary address range. When NSSA is configured,
this command will also summarize the imported Type-7 LSAs in the summary
address range.

If the local router acts as both an ABR and a router in the NSSA, this command
summarizes Type-5 LSAs transformed from Type-7 LSAs. If the router is not the
