I think this can be reproduced on simple router, where single mce(4)
interface is used as parent for several vlan(4) interfaces. E.g.
[host1] vlan100 <--> mce0.100 [gateway] mce0.200 <--> vlan200 [host2]
10.0.0.1 10.0.0.254 192.168.0.254 192.168.0.1
gateway:
sysctl net.inet.ip.forwarding=3D1
host1:
route add 192.168.0.0/24 10.0.0.254
host2:
route add 10.0.0.0/24 192.168.0.254
ping 10.0.0.1
I.e. you need to make setup, where ingress and egress interface is the
same - mce0.
