Links to third-party websites take you outside the Hewlett Packard Enterprise has no control over and is not responsible for information outside the Hewlett Enabling multicast routing on the VLAN interface to which the CLI is currently set. IP forwarding cache. Free up system resources by disabling another. To remove access restrictions, use the no form of this command. . against the TCP source port, the type of service value, or the packet's precedence. . The router uses ARP cache entries to translate bit Internet Protocol (IP) .. the route cache must be flushed so that it can be rebuilt with up-to-date routing information.
Host A and Host B are on different subnets and they have the router configured as their default gateway. If Host A wants to send a packet to Host B, it sends the packet to its default gateway. When the router makes a forwarding decision for the packet, it needs to add a new Layer 2 header as follows: Now that we know what a Layer 2 header rewrite entails, we can go ahead with our packet switching methods.
Process Switching Process switching is the oldest of the three switching methods we will be discussing in this article. It is also the slowest and we will see why. When the router receives a packet that is to be processed, the router stores this packet in memory. The router inspects the packet and places it in the input queue of the appropriate switching process, e.
When the switching process runs, it checks the routing table to determine the next-hop and outbound interface for the destination of the packet. It also determines the layer 2 address e.
Armed with this information, the switching process rewrites the layer 2 header of the packet. The packet is then sent out through the determined outbound interface.
The issue with process switching is that the process described above happens for every packet, making it quite slow. Recent IOS versions have CEF discussed later as the default switching method for IP but we can enable process switching using the no ip route-cache interface configuration command.
Process switched packets show up in IP packet debugging. Fast switched and CEF switched packets do not. A sample output of the debug is as shown below.
I received 10 of these messages in my debug output, 5 from the ping request from Host A and 5 from the ping reply from Host B. Fast Switching Fast switching improves on process switching by making use of a cache. The first packet to a destination is still process switched but the result of this switching, which includes the outgoing interface, next-hop and Layer 2 header rewrite information, is stored in the Fast Cache.
Future packets to this destination will be switched using information from the fast cache, thus improving on the speed of this switching method. We use the ip route-cache interface configuration command to enable fast switching. We can confirm that fast switching is enabled on an interface using the show ip interface command. Before I test using ping, I will check the fast cache.
Since we have not sent any packet across the router, this cache is empty. Now when I ping from Host A to Host B, notice that the first ping request packet and the corresponding ping reply packet are process switched. After this first process switching, entries are created for these destinations in the fast cache.
