Setup dummy network interfaces

sudo ip link add eth2 type dummy
sudo ip addr add 192.168.1.200/24 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

Run avahi to browse services

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

david@david-comp:~/esp/idf (feature/mdns_networking_socket)$ avahi-browse -a -r -p
