I had authentication on area 0. R4 has one interface in area 0 and another
in area 1, connected to R5. There is a virtual link between R4 and R5. The
config is straightforward: area 0 auth on both routers, and then area 1
virtual-link <neighbor ID> authentication-key cisco.
The lab solution has it configured this way and CCO recommends this
configuration. I have no clue what I'm missing here.
Thanks,
John

|
| Do any of you have any tips for configuring virtual link authentication?
| This seems to be a pretty simple config and I don't see what I'm missing.
