Usage guidelines
Configuring summary routes can reduce the size of the route table, LSPs and LSDB. Routes to be
summarized can be IS-IS routes or redistributed routes. The cost of a summary route is the smallest cost
among all summarized routes.
If no level is specified in the command, the default is level-2.

# Configure a summary route of 2002::/32.
<Sysname> system-view
[Sysname] isis
