+# Unnumbered BGP
+
+This directory contains *netlab* topology file for a two-router unnumbered BGP test lab.
+
+![BGP unnumbered topology](graph.png)
+
+After starting the lab, explore the BGP sessions, BGP tables, and IP routing tables on R1 and R2.
+
+## Changing Device Types
+
+This topology can be used with all network devices supporting unnumbered EBGP sessions, and all virtualization providers supported by *netlab*:
+
+* To change device type, use the `-d xxx` CLI argument
+* To change the virtualization provider, use `-p` CLI argument.
+
+For example, to start the lab with FRR containers, use:
+
+```
+netlab up -d frr -p clab
+```
