EIGRP Authentication still working after removing it

HI Guys,

a few days ago I have experienced an issue with eigrp md5 authentication on uplink interface. Basicaly authentication was not there but was on other nieghbors, even though neighbor with  no md5 was still learning  routes from others and neighborship never failed. Once switch 4948 was reloaded nieghborship lost and no routes have been learned. My question is why it did not fail before (authentication has been removed from interface 5 months ago) and it was working fine until last Tuesday (reload)

 

Thanks

it's not possible

it's not possible neighborship must be broken when next hello was sent. I think you are missing something with configuration part.
