# 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.
