Hi Ben,
  my network statement is a type error it should be: network area 45 not 
  network area 45

  Hello Mohamed,

For the OSPF problem, double-check your network statement... mine did 
not accept that:
Rack1SW1(config-router)#network area 45
OSPF: Invalid address/mask combination (discontiguous mask)

I would suggest changing yours to either:
network area 45
network area 45

You want to make sure that your network/wildcard mask includes the 
interface you're trying to make participate in OSPF. You can always 
check your work with the "show ip ospf interface" command.

Once your interface is included, it should take the 'neighbor' statement.

As far as the Multicast goes - I would assume you get this because there 
(by design) is not a PIM neighbor on adjacent on the VLAN. I think this 
is more of a warning than a true problem.
