RIP

• Classfull
• IGP
• Dynamic
• Distance vector
• Metric [hop count (max-15)] (doesn’t work based on bandwidth but hop count)
• Bell Man Ford Algorithm
• Maximum Path = default 4 / maximum 6
• Port no.= 520
• UDP
• Send broadcast at 255.255.255.255

 

 

RIP Timers:

·        Send updates every   30 sec

·        Invalid a route             180 sec

·        Hold time                     180 sec

·        Flush out a route        240 sec

 (if router does not send subnet mask info to the network known as classfull address)

 

Administrative Distance: It define the trusting route for a particular destination, if there are mode than one routing protocols running in a router, RP with lower AD is used)

 

RIP V2

·        Classless / VLSM

·        Authentication (optional)

·        Trigger Updates (Send update immediately, if there is change in the routing table)

·        Multicast: 224.0.0.9

·        AD = 120
