netns mac

I have successfully installed and configured tuntap (http://tuntaposx.sourceforge.net/) and it works great. By editing

/Library/Preferences/SystemConfiguration/preferences.plist
I have a virtual interface. Here it is, with two IP addresses assigned (“aliased”) to it:

CloudrasLLCsMBP:puppet l.abruce$ sudo ip a show tap0
tap0: flags=8843 mtu 1500
ether e2:97:6b:e1:81:35
inet 10.10.10.1/8 brd 10.10.10.255 tap0
inet6 fe80::4c:d456:2a90:5de3/64 secured scopeid 0xd
inet 192.168.98.100/24 brd 192.168.98.255 tap0

But that’s not what I want.

What I want is a true

veth pair
as described by http://linux-blog.anracom.com/2016/02/02/fun-with-veth-devices-linux-virtual-bri dges-kvm-vmware-attach-the-host-and-connect-bridges-via-veth/. Here’s an example that creates the virtual interfaces, a network namespace, a new bridge, etc::

NNS=WhateverYouWantToCallTheNewNetworkNameSpace
ip netns add $NNS

ip link add veth-a$NNS type veth peer name veth-b$NNS

ip link set veth-a$NNS up

ip tuntap add tap$NNS mode tap user root

ip link set tap$NNS up

ip link add br$NNS type bridge

ip link set tap$NNS master br$NNS

ip link set veth-a$NNS master br$NNS

ip addr add 10.0.0.1/24 dev br$NNS

ip link set br$NNS up

ip link set veth-b$NNS netns $NNS

ip netns exec $NNS ip addr add 10.0.0.2/24 dev veth-b$NNS

ip netns exec $NNS ip link set veth-b$NNS up

ip netns exec $NNS ip link set dev lo up
