Hi Dmitry,
Just about to change my config, but it's not going to
fix the problem for me - my area X and area 0 are
using different passwords. Both of them are type 2,
since the interface's password have been used for area
X, I have no choice but continue to use the first
method.
I can understand why it's bad to put isdn in virtual
link, because it's just the extension of area 0, but
I'd hope 'debug ip ospf monitor', 'debug dialer' or
'debug ip routing' could tell me something, but they
pretty much came out clean and give me no useful info
to work on.
Thanks,
Chang
