Hi,
One general query regarding IOS bug:
How come to know if it is some IOS bug because when looking at the bug list
in Cisco site there is a huge list.Is there some easy way to check the
possibility of IOS bug or some other bug.
Regards,
Vijay

How about changing the network type to point-to-multipoint in order
to get
rid of the neighbor commands?

I noticed the same thing when I fired up my finished IPExpert OSPF
lab
today. I asked the GS list about not being able to set a ospf
neighbor two
days ago and the solution was to get the OSPF neighbor command to
work you
need to first remove all virutal links and then add the neighbor
commands.
If this is the case how would you keep the virtual links up after a
reboot in the real CCIE lab?

Scott Morris explains it like this:
==========================================================================
It's more a feature than a bug. Basically it boils down to confusing
OSPF.
If your non-broadcast network is operating FIRST, then you can add
virtual-links. If you try to add VLs before it's operating, you may
find
config pieces begin to disappear.
Always check out "show ip ospf interface brief" to make sure you are
really running in non-broadcast or point-to-multipoint-non-broadcast
modes
which are the only two that take neighbor commands!
