OSPF Configuration Commands 179
mask
Enter the IP subnet mask.
not-advertise Enter this parameter if you do not want to advertise routes
matching the specified IP address and mask.
tag
value
Enter a tag value, which is mainly used to control advertisement of
routes via route-policy. This value can be in the range 0 to 4294967295. The
default is 1.
Description
Use the asbr-summary command to configure a summary of imported routes for
OSPF.
Use the undo asbr-summary command to cancel the summary. This is the default.
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 an ASBR in the NSSA, this command
summarizes Type-5 LSAs translated from Type-7 LSAs. If the router is not the ASBR
in the NSSA, the summarization is disabled.
Related commands: display ospf asbr-summary.
Example
