Question Of The Day: 12 May, 2008 

Topic: RIP

r1 is a high-end router running RIP on it’s connection to the low-speed router r2.  The site engineer for r2 has noticed that the routing table on r2 is losing RIP routes.  He thinks that your r1 is sending RIP updates too quickly for r2 to process.  Configure r1 to implement a 25 millisecond delay between RIP packets.

Answer:

router rip
 output-delay 25

RIP will send up to 25 RIP routes per RIP update packet.  By default, these packets will be sent with no delay between packets.  In order to implement a delay between the packets you can use the ‘output-delay’ command under the RIP process.

output-delay
