interesting phenomenon, one which makes no sense to me. sorry, I don't have configs or traces, so I hope my word is good here.
Practicing authentication of various kinds. RIPv2. R1--------R2---------R3 the authentication key chain and key strings are different on the R1-R2 link than on the R2-R3 link. all routes on all routers appear as expected. however, I am unable to ping from R1 to R3 or visa versa. when I remove authentication, save, all routes appear again, and end to end pinging occurs just fine put in authentication again, with all links using the same authentication key-string. all routes appear in all routing tables and end to end pinging occurs. question - how is it that all routes appear everywhere, but pinging is not possible when the authentication key-string is different for the different links? authentication has nothing to do with the routed protocol - only the routing protocol messages. anyone run into this one? my CCO searches were not enlightening.
