R3102-R3103-HP 6600/HSR6600 Routers Layer 3 - IP Routing Command Reference

247
• To deny/permit a route with the specified destination and mask, use rule [ rule-id ] { deny | permit }
ip source sour-addr sour-wildcard destination dest-addr dest-wildcard.
The source keyword specifies the destination address of a route, and the destination keyword specifies
the subnet mask of the route. (The subnet mask must be valid; otherwise, the configuration is ineffective.)
