# Message Router

A **Message Router** is software, which consumes a Message from one Message Channel and republishes it to a different Message Channel channel depending on a set of conditions.

With Ylem this pattern can be implemented by using "**Condition**" and "**Run pipeline**" tasks in the pipeline that acts as a receiver of external messages.

This pattern implementation can in some scenarios look similar to the [Publish-Subscribe Channel](https://docs.ylem.co/use-cases/messaging-patterns/publish-subscribe-channel) implementation.
