Setup dummy network interfaces

Note: Set two addresses so we could use one as source and another as destination

sudo ip link add eth2 type dummy
sudo ip addr add 192.168.1.200/24 dev eth2
sudo ip addr add 192.168.1.201/24 dev eth2
sudo ip link set eth2 up
sudo ifconfig eth2 multicast

Dig on a specified interface

dig +short -b 192.168.1.200 -p 5353 @224.0.0.251 myesp.local

or a reverse query:

dig +short -b 192.168.2.200 -p 5353 @224.0.0.251 -x 192.168.1.200

Run avahi to browse services

Avahi needs the netif to have the "multicast" flag set
