I've set up a tunnel:
$ ip tunnel add mytunnel mode gre remote x.x.x.x local y.y.y.y ttl 255 $ ip link set mytunnel up $ ip address add 172.17.10.2/30 dev mytunnel $ ifconfig mytunnel up
Now, I can ping
172.17.10.1, so the tunnel is up and running right. I want all of the IPs for a specified destination ,
172.29.0.0/20, to go through this tunnel. Some are binded to some VLAN interfaces locally, some remote that use me as a gateway.
$ ip ro add somedest/24 via 172.17.10.1 dev mytunnel
ping somedest -I 172.29.5.22 fails, did a
tcpdump and nothing shows up as going through the tunnel.
Am I doing it wrong? What could be the problem?
