| # This test uses standard topology for testing gretap. See |
| # mirror_gre_topo_lib.sh for more details. |
| # |
| # This tests flower-triggered mirroring to gretap and ip6gretap netdevices. The |
| # interfaces on H1 and H2 have two addresses each. Flower match on one of the |
| # addresses is configured with mirror action. It is expected that when pinging |
| # this address, mirroring takes place, whereas when pinging the other one, |
| # there's no mirroring. |
