I sent this question yesterday, but I didn't see that it made it to the
list. So sorry if somehow this makes it to the list twice.
1> I have the following configuration (only a portion shown) & everything is
working fine. The specific requirement I'm working on is MD5 authentication
in area 1. What I don't understand is that when I issue the show ip ospf
interface command it shows "Message digest authentication enabled", but "No
key configured, using default key id 0". Why does it show no key
configured?
2> When the lab asks to use MD5 authentication, does it matter encryption
type, i.e. "<0-7> Encryption type (0 for not yet encrypted, 7 for
proprietary)"?
