@miri64 Since I have not yet seen how the test should look like if it works correctly on a platform, here what I did, what I could observe, and some questions I have:
- I have two nodes and one border router.
- The first question came up when I had to compile the nodes as leaf nodes with `CFLAGS="-DGNRC_IPV6_NIB_CONF_6LN=1 - DGNRC_IPV6_NIB_CONF_6LR=0`. Otherwise, I get
nib: multihop prefix and context dissemination on router activated,
but no ABRO found. Discarding router advertisement silently
on receiption of router advertisements and the global unicast address is not set.
Is that correct?
- On the nodes, `ifconfig` shows that `RTR_ADV` option is set even though they are leaf nodes. Is that correct and do I have to execute `ifconfig 9 -rtr_adv`?
- In my network, the border router gets over its Ethernet interface the global routing prefix `2003:aaaa:bbbb:cccc::/64` from the LAN and the global unicast address `2003:aaaa:bbbb:cccc:32ae:a4ff:fe47:4ccd`.
- When I use `ifconfig 9 add unicast 2001:db8::1/64`, the leaf nodes get the global unicast addresses `2001:db8::32ae:a4ff:fe18:7a3d` and `2001:db8::32ae:a4ff:fe41:60f9`
- On router, `nib route` gives
2003:aaaa:bbbb:cccc::/64 dev #6
2001:db8::/64 dev #9
default* via fe80::1 dev #6
- On the nodes, `nib route` gives
default* via fe80::32ae:a4ff:fe47:4ccd dev #9
- Pinging from one node the other node with `ping6 2001:db8::32ae:a4ff:fe18:7a3d` doesnt work. The reason seems to be that the source node is using rather its link local address than its global unicast address. On the route, I can see the following message:
ipv6: Received (src = fe80::32ae:a4ff:fe41:60f9, dst = 2001:db8::32ae:a4ff:fe18:7a3d, next header = 58, length = 12)
So it is probably the a problem of `esp_now`.
