4# This test uses standard topology for testing gretap. See
5# mirror_gre_topo_lib.sh for more details.
6#
7# Test for mirroring to gretap and ip6gretap, such that the neighbor entry for
8# the tunnel remote address has invalid address at the time that the mirroring
9# is set up. Later on, the neighbor is deleted and it is expected to be
10# reinitialized using the usual ARP process, and the mirroring offload updated.
