> RIP: ignored v2 update from bad source 150.50.7.7
You're showing bad update addresses, from .7.5 and .7.7 on the fa0/0
interface. Is there a typo in your address, your fa0/0 shows .17.2 for the
last two octets?
I would guess the invalid address is preventing the auth failure message.
Try either changing the address of the interface or adding no validate
update-source, and see if you see the authentication failure then.
