3.5.2 Dynamic Routing (RIP)

 DSR- 150/150N/250/250N does not s upport RIP.

Setup > Internet Settings > Routing Mode

Dynamic routing us ing 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 d ynamic

adjus tment of routing tables in order to adapt to modifications in the LAN without

interrupting traffic flow.

The RIP direction will define how this router s ends and receives RIP packets .

Choos e between:

 Both: The router both broadcas ts its routing table and als o proces s es 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

broadcas t its routing table.

 None: The router neither broadcas ts its route table nor does it accept any

RIP packets from other routers. This effectively dis ables RIP.

 The RIP vers ion is dependent on the RIP s upport of other routing

devices in the LAN.

 Disabled: This is the s etting when RIP is disabled.

 RIP-1 is a clas s -bas ed routing version that does not include s ubnet

information. This is the mos t commonly supported version.

 RIP-2 includes all the functionality of RIPv1 plus it s upports s ubnet

information. Though the data is s ent in RIP-2 format for both RIP-2B and

RIP-2M, the mode in which packets are sent is different. RIP-2B broadcas ts

data in th e entire s ubnet while RIP-2M s ends data to multicas t addres s es .

If RIP-2B or RIP-2M is the selected version, authentication between this router and

other routers (configured with the same RIP vers ion) is required. MD5

authentication is used in a firs t/s econd key exchange proces s . The authentication

key validity lifetimes are configurable to ens ure that the routing information

exchange is with current and s upported routers detected on the LAN.
