Use the undo aggregate command to disable this function.
By default, no route is aggregated.
Use the aggregate command without parameters to create one local aggregated 
route and set atomic aggregation attributes.
Example
# Create an aggregation entry in the MBGP routing table, with aggregated route 
address as 192.213.0.0.

Parameter

Description
Use the compare-different-as-med command to enable to compare the route 
MED values of neighbors from different ASs.
Use the undo compare-different-as-med command to disable this function.
By default, the comparison function is disabled.
If there are multiple routes available to the same destination address, you can 
select the route with the smallest MED value.
This command is not recommended unless you make sure that different ASs use 
the same IGP and route selection modes.
Example
# Enable to compare the route MED values of neighbors from different ASs.
