Description After the summarization of redistributed routes is configured, if the local router is an
autonomous system border router (ASBR), this command summarizes the
redistributed Type-5 LSAs in the summary address range. When NSSA is configured,
this command will also summarize the redistributed Type-7 LSAs in the summary
address range.
If the local router acts as both an ABR and a switch router in the NSSA, this command
summarizes Type-5 LSAs transformed from Type-7 LSAs. If the router is not the router
in the NSSA, the summarization is disabled.
