+# MPLS LDP + BGP-LU Lab
+
+This lab combines LDP within AS 65000 with BGP LU across three autonomous systems (AS 65000, AS 65101 and AS 65102):
+
+![BGP sessions](topology.bgp.png)
+
+The central autonomous system has a route reflector and a P-router that is not running BGP:
+
+![Physical lab topology](topology.link.png)
+
+The lab topology uses a mix of Cisco IOSv and Arista vEOS devices with *libvirt* provider.
+
+To test MPLS configuration module with other devices without changing the lab topology file, change the PE1 device type with `-s` argument of **netlab up** command:
+
+```
+netlab up -s nodes.pe1.device=<type>
+```
