+- Create topology (setup module)
+- Bring up topology
+- Verify BGP convergence

+2. Test aspath attribute and verify best path is installed as per
+   shortest AS-Path
+3. Test localpref attribute and verify best path is installed as per
+   shortest local-preference
+4. Test weight attribute and and verify best path is installed as per
+   highest weight
+5. Test origin attribute and verify best path is installed as per
+   IGP>EGP>INCOMPLETE rule
+6. Test med attribute and verify best path is installed as per lowest
+   med value
+7. Test admin distance and verify best path is installed as per lowest
+   admin distance
+
+Teardown module:
+- Bring down the topology
+- stop routers
