Hi,  I figured out a problem with the BIRD routing daemon.  It is not possible to route BGP via IPIP tunnels. As you can see below  the packets will be routed through the wrong device. Normally it should  choose "ASIX" as right device, but it does not.  root@cr01:/etc/bird# ip -6 route | grep 2a06:8187:fe48::/48  2a06:8187:fe48::/48 via 2a06:8187:fe01:100::2 dev vlan1000  proto bird   src 2a06:8187:fe01::2  metric 1024  pref medium  The interface configuration is the following:  iface ASIX inet manual       pre-up ip -6 tunnel add ASIX mode any local 2a07:59c6:d007::1  remote 2a00:1ca8:2a::730 ttl 255       pre-up ip link set dev ASIX mtu 1476       pre-up ip link set dev ASIX up       pre-up ip address add 89.46.125.149/30 dev ASIX       pre-up ip address add 2a06:8187:fe01:100::1/56 dev ASIX       post-down ip -6 tunnel del ASIX  root@cr01:/etc/bird# birdc6 -v  0001 BIRD 1.6.3 ready.  bird>  Maybe you can help me here?  Kind regards.  Joey
