RIP V2 MD5 authentication
Hi, I want to implement RIP V2 MD5 authentication in an existing network. RIP V2 is up and running already. If I turn on MD5 authenticattion on a router or switch, will it lose connectivity with the rest of the network until I can turn on authentication on the rest of the network devices.

It may seem a stupid question, why are you using RIP in particular?
no this will not loose the connectivity until unless you configured it for auth required mode.
It won't lose the connection immediately .But after you enable MD5 into router it'll generate error "Invalid Authentication".If you debug then you can see this error.
#debug ip rip
After few seconds routes will become down and it'll show : Routes are possibly down.Then after few moments routes will be deleted by flush timers.

so rigan123, you're saying that it will loose connectivity?(few Seconds)?
It'll live few moments.Then after few moments it'll become down completely.Because flush timers will update "Invalid Authentication" error.Your existing routes will be deleted too.

so how would you recommend doing this?
