level-1: Configure to aggregate the routes imported into Level-1.
level-2: Configure to aggregate the routes imported into Level-2 routing table.
level-1-2: Configure to aggregate the routes imported into Level-1 and Level-2.

Description
Using summary command, you can configure IS-IS route summary. Using undo
summary command, you can cancel the summary.
By default, no routes will be summarized.
Similarly, the routes with the same next hops can be aggregated into one route. In this
way, the sizes of the routing table, LSP packets and LSDB are reduced. Among them,
the aggregated route can be either a route found by IS-IS protocol, or an imported route.
Furthermore, the cost value of the aggregated route adopts the smallest cost of the
routes aggregated.
Example
# Set a route summary of 202.0.0.0/8.
[Quidway-isis] summary 202.0.0.0 255.0.0.0
