If no level is specified, the command applies to Level-2.
You can summarize routes with the same next hop into a single route to reduce the size of the routing
table, as well as the size of the LSDB. This command can summarize both learned and redistributed IPv6
IS-IS routes. The cost of the summary route is the smallest cost of those summarized routes.
Examples
# Configure a summary route of 2002::/32.
