Chapter 15 Routing Protocols
15.1 RIP
The entries in the routing table can be defined statically or the routing table can be updated
constantly by dynamic exchange of routing information between several devices. This ex-
change is controlled by a Routing Protocol, e.g. RIP (Routing Information Protocol). By de-
fault, about every 30 seconds (this value can be changed in Update Timer), a device
sends messages to remote networks using information from its own current routing table.
The complete routing table is always exchanged in this process. If triggered RIP is used, in-
formation is only exchanged if the routing information has changed. In this case, only the
changed information is sent.
Observing the information sent by other devices enables new routes and shorter paths for
existing routes to be saved in the routing table. As routes between networks can become
unreachable, RIP removes routes that are older than 5 minutes (i.e. routes not verified in
the last 300 seconds - Garbage Collection Timer + Route Timeout). Routes learnt with
triggered RIP are not deleted.
Your device supports both version 1 and version 2 of RIP, either individually or together.
