+
+2. Adapt your netplan configuration to set the following:
+
+```yaml
+network:
+  version: 2
+  renderer: networkd
+  ethernets:
+    enp2s0:
+      dhcp4: no
+  bridges:

+      dhcp4: yes
+      interfaces:
+         - enp2s0 # Set to your interface
+```
+
+
+3. Apply netplan configuration:
+
+```bash
+sudo netplan apply
+```
+
+
+4. Get the state and the list of bridges in the system:
+
+```bash
+sudo brctl show
+
+# Or
+ip link show type bridge
