Usage guidelines
You can use this command to filter redistributed routes as needed.
To reference an advanced ACL (with a number from 3000 to 3999) in the command, configure the ACL
in one of the following ways:
• 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.
