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.
