The point of having a switch usually would be that it would be VLAN 802.11q aware, and take care of VLAN tagging.
If you use a hub, if you’re running 802.11q VLANs, the NICs will have to be 802.11q aware.
If it’s vanilla ethernet, then Bob’s your uncle.

thank you for the quick response….
the hub would be dedicated for the multicast traffic
only 2 ports would be used.. 1 for router B and the other for router C

A hub will work, but of course all traffic on all hub ports is contending for the same bandwidth, so performance may suffer if you have other devices on the hub.
A switch configured for multicast would give better performance since the multicast, as well as unicast traffic, would only be sent out ports where needed.
