### Bridge driver options ### Bridge driver options
When creating a custom network, the default network driver (i.e. `bridge`) has When creating a custom `bridge` network, the following additional options can
additional options that can be passed. The following are those options and the be passed. Some of these have equivalent flags that can be used on the dockerd
equivalent Docker daemon flags used for docker0 bridge: command line or in `daemon.json` to configure the default bridge, `docker0`:
