ip l add dev tun type gretap external ip r a 10.0.0.1 encap ip dst 192.168.152.171 id 1000 dev gretap For gretap Key example when the command set the id but don't set the TUNNEL_KEY flags. There is no key field in the send packet In the lwtunnel situation, some TUNNEL_FLAGS should can be set by userspace Signed-off-by: wenxu <wenxu@ucloud.cn> Signed-off-by: David S.
