my network statement is a type error it should be: network 18.104.22.168 0.0.0.255 area 45 not
network 22.214.171.124 0.0.0.5 area 45

For the OSPF problem, double-check your network statement... mine did
not accept that:
Rack1SW1(config-router)#network 126.96.36.199 0.0.0.5 area 45
OSPF: Invalid address/mask combination (discontiguous mask)
I would suggest changing yours to either:
network 188.8.131.52 0.0.0.255 area 45
network 184.108.40.206 0.0.0.0 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.
