In combination with VMware on a Linux host some additional aspects are interesting: Just use this command: Docker and Linux Networking: We shall come back to this point below. Or am I trying something that isn’t possible? Now you give IP addresses to brm and to vm2 Provide details on that.

Network namespaces change that fundamental assumption. Virtual Ethernet interfaces come in pairs, and they are connected like a tube—whatever comes in one veth interface will come out the other peer veth interface.
Furthermore related host routes are automatically set. Question better on superuser. Especially, when you want to avoid address assignment to the bridges themselves. We do not need to establish firewall-rules on the vth itself – which has security implications if only done on level 3 – but on an “external” Ethernet device.

Or am I trying something that isn’t possible?
Virtual networking devices in Linux – Stack Overflow
The host “mytux” shall be attached via a regular bridge port to only one of the bridges. I’d like to do it without LXC if possible.
As I discovered after publishing this post, it most certainly is possible to assign various types of network interfaces to network namespaces, including physical interfaces. Tap device is logical net device but have different with any other one: Add namespaces ip netns add ns1 ip netns add ns2 ip netns add ns3 ip netns add ns4 ip netns add vetn ip netns add ns6 Add veths ip link add eth0 type veth peer name eth1 ip link add eth2 type veth peer name eth3 ip link add eth4 type veth peer name eth5 ip link linix eth6 type veth peer name eth7 ip link add eth8 type veth peer name eth9 link veths ip link set netns ns1 eth0 ip link set netns ns2 eth3 ip link set netns ns3 eth6 ip link set netns ns4 eth9 ip link set netns ns5 eth1 ip link set netns ns5 eth2 ip link set netns ns5 eth4 ip link set netns ns6 eth5 ip link set netns ns6 eth7 ip link set netns ns6 eth8 assign mac’s ip netns exec ns1 ifconfig eth0 hw ether According to our example we shall attach the host now by the use of a veth-pair to virbr4.
The virtual bridge device itself – in its role as an Ethernet device – does not work in promiscuous mode. To my knowledge neither the “wicked” service used by Opensuse nor the “ifcfg This scenario of a virtual network inside a host is a bit academic. As was said in comments, it’s probably better to just keep those already randomly, and correctly, generated.
Then we implement and configure 2 KVM Linux guests here Kali systems – one with an Ethernet interface attached to “vibr4”; the other guest will be connected to “virbr6”. I have created 6 namespaces and configured them with veth links. We shall later configure addresses of the guests manually; you will find some remarks on a specific, network wide DHCP service at the end of the article. Configuring Interfaces in Network Namespaces Now that veth1 has been moved to the blue namespace, we need to actually configure that interface.
With the spanning tree protocol activated all physical systems attached to the network behind each physical interface may communicate with physical or virtual guests linked to the bridge by other physical interfaces or virtual ports.
