Walkthrough of how routing works in a virtual network, what route server is and how it works with your various NVAs.

IMPORTANT NOTE. 22:50 This 0.0.0.0/0 would be the default route for everything. This would NOT impact traffic WITHIN the VNet, i.e. subnet to subnet, rather everything else not for the VNet. Even if a firewall sends more specific VNet routes to a route server, when the route server plumbs down these routes, they’ll be ignored by the SDN stack meaning VM to VM traffic within the VNet would not use this NVA as a hop. You would need to use UDR.
