Filter-Policy Import - HP 5920 Series Command Reference Manual

Usage guidelines
To use an advanced ACL (with a number from 3000 to 3999) in the command, configure the ACL using
one of the following methods:
To deny/permit a route with the specified destination, use the rule [ rule-id ] { deny | permit } ip
•
source sour-addr sour-wildcard command.
• To deny/permit a route with the specified destination and mask, use the rule [ rule-id ] { deny |
permit } ip source sour-addr sour-wildcard destination dest-addr dest-wildcard command.
The source keyword specifies the destination address of a route and the destination keyword specifies the
subnet mask of the route. The specified subnet mask must be contiguous. Otherwise, the configuration
does not take effect.
