 ## Description
+
 A lab consists of an SR Linux node connected with Juniper vMX via a point-to-point ethernet link. Both nodes are also connected with their management interfaces to the `clab` docker network.
 
 Juniper vMX VM is launched as a container, using [vrnetlab integration](../manual/vrnetlab.md).

 ## Use cases
+
 This lab allows users to launch basic interoperability scenarios between Nokia SR Linux and Juniper vMX network operating systems.
 
 The lab directory [contains](https://github.com/srl-labs/containerlab/tree/main/lab-examples/vr02) files with essential configurations which can be used to jumpstart the interop demonstration.
