In Linux, how can you create 3 virtual interfaces that are bridged together through a virtual switch so that they can ping6 each other?
What I did:
tunctl -t tap1i
tunctl -t tap2i
tunctl -t tap3i
ip addr add scope link fd80::1/56 dev tap1i
ip addr add scope link fd80::2/56 dev tap2i
ip addr add scope link fd80::3/56 dev tap3i
ip link set dev tap1i up
ip link set dev tap2i up
ip link set dev tap3i up
brctl addbr r2
brctl addif r2 tap1i tap2i tap3i
The problem is that brctl showstp r2 shows the ports as "disabled" instead of "forwarding" as expected, and ping doesn't work.
What I want is for ping6 -I tap1i fd80::2 to work.
Thanks.
