4.5.31 Dynamic Routing
Dynamic Routing allows the ADSL Router to automatically adjust to physical changes in the
network. The ADSL Router, using the RIP protocol, determines the network packets’ route
based on the fewest number of hops between the source and the destination. The RIP protocol
regularly broadcasts routing information to other ADSL Routers on the network. The Direction
determines the direction that RIP routes will be updated. Selecting In means that the ADSL
Router will only incorporate received RIP information. Selecting Out means that the ADSL
Router will only send out RIP information. Selecting Both means that the ADSL Router will
incorporate received RIP information and send out updated RIP information.
The protocol is dependent upon the entire network. Most networks support RIP v1. If RIP v1 is
selected, routing data will be sent in RIP v1 format. If RIP v2 is selected, routing data will be
sent in RIP v2 format using subnet broadcasting. If RIP v1 Compatible is selected, routing data
will be sent in RIP v2 format using multicasting. See Figure 1-50.
