
DSR- 150/150N/250/250N does not support RIP.

Dynamic routing using the Routing Information Protocol (RIP) is an Interior Gateway Protocol (IGP)
that is common in LANs. With RIP this router can exchange routing information with other
supported routers in the LAN and allow for dynamic adjustment of routing tables in order to adapt to
modifications in the LAN without interrupting traffic flow.
The RIP direction will define how this router sends and receives RIP packets. Choose between:

Both: The router both broadcasts its routing table and also processes RIP information
received from other routers. This is the recommended setting in order to fully utilize RIP
capabilities.

Out Only: The router broadcasts its routing table periodically but does not accept RIP
information from other routers.

In Only: The router accepts RIP information from other routers, but does not broadcast its
routing table.

None: The router neither broadcasts its route table nor does it accept any RIP packets from
other routers. This effectively disables RIP.

Disabled: This is the setting when RIP is disabled.

RIP-1 is a class-based routing version that does not include subnet information. This is the
most commonly supported version.

RIP-2 includes all the functionality of RIPv1 plus it supports subnet information. Though
the data is sent in RIP-2 format for both RIP-2B and RIP-2M, the mode in which packets are
sent is different. RIP-2B broadcasts data in the entire subnet while RIP-2M sends data to
multicast addresses.
If RIP-2B or RIP-2M is the selected version, authentication between this router and other routers
(configured with the same RIP version) is required. MD5 authentication is used in a first/second key
exchange process. The authentication key validity lifetimes are configurable to ensure that the
routing information exchange is with current and supported routers detected on the LAN.

The RIP version is dependent on the RIP support of other routing devices in the
LAN.
