Description
Use the
abr-summary
command to configure a summary route on the area border router.
Use the
undo abr-summary
command to remove a summary route.
By default, no route summarization is configured on an ABR.
You can enable advertising the summary route or not, and specify a route cost.
This command is usable only on an ABR. Multiple contiguous networks may be available in an area,
where you can summarize them into one network on the ABR for advertisement. The ABR advertises
only the summary route to other areas.
