Hi All,

I run into a strange problem with ospf virtual link & authentication:

r1 ---- r2 ---- r3

r1's lo int is in area 4
link between r1 and r2 is in area 3
link between r2 and r3 is area 0

Virtual link is configured on r2 and r3 for area 4 use area 3 as transit
area. For learning purpose, I configured area 0 to use md5 authentication,
as soon as I configured that, the virtual link is not longer working. Then I
tried the 'message-digest-key' option with the 'area virtual' command, but
still doesn't work.

Any ideas?

Thanks in advance for your response.
