Unicast over Eigrp neighborship

I have three routers connected in a triangular fashion (Each router
connected with other 2 routers through serial) and eigrp is running
between three of them (Neighborship is up between the three routers).

Now further, if i create static neighborship (using "neigbor" command)
between any two of the routers then would the neighborship with the
remaining 3rd router will get down automatically because static
neigborship will disable the multicast on the
eigrp enabled interfaces routers.

I was doing this on GNS but neighborship between routers is still up,
please let me know what is the reason behind this, am i doing anything
wrong.
