IP Routing—Configuring Static Routes
Enabling Fast Caching
For example:
ProCurve(config)# int eth 0/1
ProCurve(config-eth 0/1)# no ip route-cache
Note Fast caching is forcibly disabled when you use the following processes:
■ the ProCurve Secure Router OS firewall
■ any firewall processes, such as ACLs and ACPs
■ policy based routing (PBR)
If you enable the firewall, the ProCurve Secure Router must use process
switching because firewall features require the router to make more-extensive
computations than simple route determination, including checks for attacks
and packet filtering according to an access policy. Similarly, PBR requires the
router to screen packets to determine whether to route them according to a
route map or according to the routing table.
To optimize packet switching for firewall processes, the ProCurve Secure
Router uses a separate table so that it does not have to check long ACLs
each time it receives a packet. This table speeds up firewall computations.
