See 5# mirror_gre_topo_lib.sh for more details. 6# 7# Test for "tc action mirred egress mirror" when the device to mirror to is a 8# gretap or ip6gretap netdevice. Expect that the packets come out encapsulated, 9# and another gretap / ip6gretap netdevice is then capable of decapsulating the 10# traffic.
