Parameter 
None 
Description 
Use the summary command to configure auto aggregation of sub-network routes. 
Use the undo summary command to disable auto aggregation of sub-network routes. 
By default, no auto aggregation of sub-network routes is executed.  
After the summary is configured, BGP cannot receive the sub-network routes imported 
from the IGP, so the amount of the routing information can be reduced.  
Example 
# Make the auto aggregation of the sub-network routes.
