Route Table // Multicast Traffic


Currently have two physical workstations and one virtual machine. The host operating system is Windows 10, with a guest operating system of Red Hat Linux. The other workstation is also running Red Hat Linux.

The host workstation has two network interface cards, with one connected to the domain network (10.111.1.0), and the other network interface card is multi-homed with several different IP addresses.

My understanding is that the only multicast traffic should be sent over the second network interface. However, I see that the primary network interface is also routing multicast traffic.

On top of ensuring the only multicast traffic is sent over the second network interface card, the IP addresses assigned to the second interface card should also be routed to the corresponding network.

I have found that when I remove the domain network cable from the workstation, I lose connectivity with some of the IP addresses that should only be routed on the secondary network interface.

I have provided the routing table from Windows below, would anyone mind taking a look and letting me know if there is something off? I have read that Windows has removed the 'primary' 'secondary' network interface concept, but somehow traffic is still following a precedence.

Any help would be greatly appreciated, if you have any questions, please don't hesitate to ask.
