+## Description
+A lab consists of an SR Linux node connected with FRR router via a point-to-point ethernet link. Both nodes are also connected with their management interfaces to the `clab` docker network.

+
+## Use cases
+This lab allows users to launch basic control plane interoperability scenarios between Nokia SR Linux and FRR network operating systems.
+
+The lab directory [contains](https://github.com/srl-wim/container-lab/tree/master/lab-examples/srlfrr01) files with essential configurations which can be used to jumpstart the interop demonstration.
