I'd like to setup three virtual network interfaces (veth) which can communicate with each other. To simulate a three node cluster, each program then binds to one veth interface. I'd like to do it without LXC if possible. I tried using: Created three veth pairs: sudo ip link add type veth Created a bridge sudo brctl addbr br0 Added one of each pair to the bridge: sudo brctl addif br0 veth1 sudo brctl addif br0 veth3 sudo brctl addif br0 veth5 Configured the interfaces: sudo ifconfig veth0 10.0.0.201 netmask 255.255.255.0 up sudo ifconfig veth2 10.0.0.202 netmask 255.255.255.0 up sudo ifconfig veth4 10.0.0.203 netmask 255.255.255.0 up Then I verified if is works using: ping -I veth0 10.0.0.202 but it doesn't :( The I added IP addresses to the veth1,veth3,veth5 and br0 interfaces in the 10.0.1.x/24 range. But that doesn't help. Any ideas? or a guide, all I find in how to use it with LXC. Or am I trying something that isn't possible?
