Chapter 3 OSPF Configuration Commands
3Com Corporation
3-3
Description
Use the asbr-summary command to configure summarization of redistributed routes
by OSPF.
Use the undo asbr-summary command to cancel the summarization.
By default, summarization of redistributed routes is disabled.
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.
Related command: display ospf asbr-summary.
