두 개의 이더넷 인터페이스를 연결할 수 없습니다

내 /etc/network/interfaces 파일은 다음과 같습니다

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

auto enp0s3
 iface enp0s3 inet dhcp 

auto enp0s8
iface enp0s8 inet static
  address 172.16.3.1
  netmask 255.255.255.0
  network 172.16.3.0
  broadcast 172.16.3.255

auto br0
iface br0 inet static
  address 172.16.3.1
  network 172.16.3.0
  netmask 255.255.255.0
  broadcast 172.16.3.255
  bridge-ports enp0s3 enp0s8

또한 여기에 내 ifconfig -a결과 가 있습니다.

그런데 막상 하려고 해도 ping -I enp0s8 192.168.0.1아무런 대답이 돌아오지 않습니다. 또한 enp0s3 인터페이스의 tcpdump에는 아무것도 표시되지 않습니다. 내가 무엇을 놓치고 있는지 조언해 주실 수 있나요?

IP 주소는 구성 포트가 아닌 브리지 인터페이스에만 배치되어야 합니다.
