Can no longer ping containers after setting TBF qdisc on Docker0

I am trying to use the tc command to manipulate traffic on the docker0 interface. I run the commands
tc qdisc del dev docker0 root
tc qdisc add dev docker0 root handle 1: tbf rate 100mbps burst 1600 limit 1
I believe this is what it does: - tbf: Specifies the TBF qdisc to be used. - rate 100mbps: Sets the maximum bandwidth rate to 100 Mbps for the docker0 interface. - burst 1600: Sets the maximum amount of data that can be transmitted in a single burst to 1600 bytes. - limit 1: Limits the token bucket size to 1 token, which limits the amount of data that can be sent at any given time to the burst size. However, after setting this rule, I can no longer ping containers that are already running and attached to the default docker0 interface. I can also no longer build images that contain commands such as RUN apt-get update -y. Why is this the case. Can this qdisc configuration not be used alone?
