How to setup networks for Failover Clustering / Hyper V.

I currently have four networks:

Managment
LiveMigration
CSV
VMAccess

Do I setup virtual switch for each network in Hyper V? How does CSV traffic know to route through CSV network?

Is there any good videos or documentation available to setup networks? Most of the documents I have found are too cryptic.

Usually, you need a virtual switch only for the networks that are being used by your virtual machines (might be Management and/or dedicated infrastructure/VM network). It is not recommended to use LiveMigration and CSV networks for something else (these should be held dedicated).

Here are good articles on the matter:

Thanks for the info.

I created a Virtual Switch Manager for "VMAccess" but I dont see the network listed in Failover Cluster Networks. Should it be listed? In failover cluster networks I do see Mgmt, LiveMigration, and CSV.

If you created the switch for use only by VMs and not by the host, then, no, the switch will not be seen by the cluster because the cluster does not have any virtual NICs connected to the switch. The Mgmt, LiveMigration, and CSV networks are all defined specifically as cluster resources.
