I know it may seem a little obvious, so at the risk of insulting your
intelligence, have you tried 'debug ip ospf adj' on both sides to see
what the error(s) are?
FWIW, I copied your configs directly into a couple of 2600s and there
was an extra space behind "ip ospf message-digest-key 2 md5 IpExPeRt_6
" on R6.
