### General
|
||||
|
||||
Traefik creates, for each consul Catalog service, a corresponding [service](../services/index.md) and [router](../routers/index.md).
|
||||
|
||||
The Service automatically gets a server per container in this consul Catalog service, and the router gets a default rule attached to it, based on the service name.

The Service automatically gets a server per instance in this consul Catalog service, and the router gets a default rule attached to it, based on the service name.
|
||||
|
||||
### Routers
|
||||
|
||||
To update the configuration of the Router automatically attached to the container, add labels starting with `traefik.routers.{name-of-your-choice}.` and followed by the option you want to change.

For example, to change the rule, you could add the label ```traefik.http.routers.my-container.rule=Host(`mydomain.com`)```.
