modifying the attributes of routing information.
Perform the following configuration in route-policy view.
By default, no apply clause is defined.
Note that, if the apply cost-type internal clause is defined for a route-policy
node, when all the matching conditions of the node are met, IGP cost will be used

apply cost clause takes precedence over the apply cost-type internal clause,
while the latter takes precedence over the default med command.
Defining an IP Prefix List An ip-prefix (IP prefix list) is identified by its ip-prefix name. Each ip-prefix can
include multiple items, and each item, identified by an index-number, can
