Does Md5 affect convergence?

The ping tests were done on the same topology used on (14/07/12) my last post.

Md5 Authentication on Routers in same EIGRP AS seems not to change the speed  of convergence. As revealed by the ping results above and wireshark results. There’s need to check whether it does on the other routing protocols. I think it does on RIP. 

Can you guys run the tests on the topology attached previously.

Wireshark was enabled to capture results on R2 interface S1/1 and R4 int S1/0 .

200 Pings were being sent from R5 to Lo1 address 1.1.1.1 of R1

Interface S1/0 of R2 would be shut during the pings.

This should be repeated 10 times and all results captured.

I will wait to hear your findings as well.

Thanks
