md5 authentication for OSPF

Hi All,

researching out MD5 authentication for OSPF yields the following two methods:

ip ospf message-digest-key keyid md5 key (used under the interface)

area area-id authentication message-digest (used under "router ospf
<process-id>")

I am assuming that if an interface is a Frame-Relay with multiple
frame-relay map statements for spokes, that
MD5 authentication must also be used on ALL spokes?

Is there a way to just enable MD5 authentication to a particular neighbor
in a hub and spoke environment? I'm working
on a lab that says that I have to set up the hub with a physical interface
with frame-relay map statements to two spokes (all three routers in Area
0), and then it says to configure MD5 authentication to only one of the
spokes - I'm not sure this is possible.

Thanks,

Julie Ann
