I would say this is partially true. The virtual-link will be considered
an extension of area 0, but you do not necessarily "need" to use clear
text authentication across it.
Let's say you have authentication enabled on area 0, but do not want to
do authentication across the virtual-link?
area 10 virtual-link <router-id> authentication null
or maybe you want to do md5 authentication across the virtual-link?
area 10 virtual-link <router-id> authentication message-digest
message-digest-key <key-id> md5 <key>
The specific link authentication configuration will override the area
authentication configuration for that link.

Subject: Question on using Authentication over Virtual Links
hello,
a virtual link is an extension to area 0. So if I had three routers that
where in a hub and spoke network that where connected via area 10. And
one
of the spokes was connected to area 0. And I where using clear text in
area
0 and message digest in area 10. I believe I would need to use clear
text
auth over the virtual link since it is an extension to area 0 even
though it
is physically connected to routers that are using message digest to
connect
to each other. Is this a correct assumption ?
Thanks,
