Consul Docker image with bridge mode

[oxycash]

Can we not use docker image in bridge mode ? whenever we not use host network, it joins cluster and says

sudo docker run --rm -p 8300:8300/tcp -p 8300:8300/udp -p 8301:8301/tcp -p 8301:8301/udp -p 8302:8302/tcp -p 8302:8302/udp -p 8500:8500/tcp -p 8500:8500/udp -p 8501:8501/tcp -p 8501:8501/udp -p 8502:8502/tcp -p 8502:8502/udp -it consultest:latest /bin/sh

Does serf lan use udp unicast or is it multicast/broadcast?
