I created a docker network like

docker network create --opt “com.docker.network.driver.mtu”=“1450"\
   “${DOCKER_NETWORK_NAME}” || true

and I thought the

cni0

on the k3d server node will have mtu set to

but I see its set to

🤔

I see the

mtu

value I set lands in

eth0      Link encap:Ethernet  HWaddr 02:42:AC:13:00:04  
          inet addr:172.19.0.4  Bcast:172.19.255.255  Mask:255.255.0.0
