RE: RIP v2 SLEEP TIMERS

Just one last thing. I don't think that this timer corresponds to anything
specified in RFC 2453.

See page 29 on the relationship between triggered updates and regular
updates.

http://tools.ietf.org/html/rfc2453#page-29

Could it be that this command is available simply out of programming
"laziness" or practicality ...?

I.e. the command was implemented for IGRP but it was too much work to
re-write for RIP and remove the "sleeptime" option ... ?

That is the best reason I can think of ...

Thanks and Regards

Hi Shogo,

I repeated the test after having correcting the configuration.

"timers basic 30 180 240 30000"

The feature still does not seem to be working.

============= Diagram ================

R1-(Eth3/0)---------(Eth3/0)-R2

============ configuration ===========

! R1

router rip

 version 2

 timers basic 30 180 240 30000

 passive-interface default

 no passive-interface Ethernet3/0

 network 10.0.0.0

 no auto-summary

! R2

router rip

 version 2

 timers basic 30 180 240 30000

 passive-interface default

 no passive-interface Ethernet3/0

 network 10.0.0.0

============ debug =====================

! Regular update 1

========= Interpretation ===============

Regular update 2 should have been postponed to about 08:57:09.

Instead it falls within 30 seconds (+- 5 seconds) from Regular update 1

Thanks
