Turbo Flooding of UDP Datagrams on Cisco 7200 Series Routers
Turbo Flooding of UDP Datagrams on Cisco 7200 Series Routers
Description
Turbo flooding is now supported on Cisco 7200 series routers. Turbo flooding speeds up flooding of User Datagram Protocol (UDP) datagrams using the spanning-tree algorithm. This feature is useful for quickly downloading periodic updates from a server to multiple clients in an environment where updates are frequent and speed and latency are primary considerations.
Configuration Tasks
To use the turbo flooding feature, refer to the "Speed Up Flooding of UDP Datagrams" section in the "Configuring IP" chapter of the Network Protocols Configuration Guide, Part I. For additional information, refer to the "Configure Broadcast Packet Handling" section in the "Configuring IP" chapter of the Network Protocols Configuration Guide, Part I.
Configuration Examples
The following example enables turbo flooding on a Cisco 7200 series router. Bridging must be configured on each interface that is to participate in the flooding. If bridging is not configured on an interface, the interface will never forward broadcasts it receives, and the router will never use the interface to send broadcasts received on a different interface.
router# configure terminalrouter (config)# ip forward-protocol udprouter (config)# ip forward-protocol spanning-treerouter (config)# ip forward-protocol turbo floodrouter (config)# exitrouter#
Note
For additional examples, refer to the "Broadcasting Examples" section in the "Configuring IP" chapter of the Network Protocols Configuration Guide, Part 1.
Command Reference
For information on the turbo flooding feature, refer to the ip forward-protocol turbo-flood command in the "IP Commands" chapter of the Network Protocols Command Reference, Part I.
