"""
Following tests are covered to test BGP Multi-VRF Dynamic Route Leaking:
1. Verify that with multiple tenant VRFs, dynamically imported routes are
    further advertised to eBGP peers.
2. Verify the route-map operations along with dynamic import command
3. Verify that deleting static routes from originating VRF also deletes
    routes from other VRFs and peers.
4. Verify that deleting and adding "import" command multiple times shows
    consistent results.
