HI Alain,             (I will not forget to rate) It's a configuration in a lab. The cisco is connected via the lan interface fa0/0 debug output: Router# *Mar  1 01:43:16.831: RIP: received packet with text authentication romeo *Mar  1 01:43:16.835: RIP: ignored v2 packet from 172.16.0.254 (invalid authentication) *Mar  1 01:43:24.791: RIP: sending v2 update to 224.0.0.9 via FastEthernet0/0 (172.16.0.2) *Mar  1 01:43:24.795: RIP: build update entries - suppressing null update *Mar  1 01:43:46.115: RIP: received packet with text authentication romeo *Mar  1 01:43:46.119: RIP: ignored v2 packet from 172.16.0.254 (invalid authentication) Router#sh run int fa0/0 Building configuration...

I hope this will help you. Hans       ... View more
