This is probably an issue for all prefixes served by the border router (on and off mesh).

I found a work-around… I set up this script to run at boot:
root@wsg-74fe481fe117:~# cat /usr/local/bin/recommission-ncp
#!/bin/sh
ROUTER_CONFIG='{
"networkKey":"aabbccddaabbccddaabbccddaabbccdd",
"prefix":"fdaa:bbcc:ddee:ff00::",
"defaultRoute":true,
"extPanId":"0011223344556677",
"panId":"0x0123",
"passphrase":"0123012301",
"channel":1,
"networkName":"MyNetwork"
}'
wpanctl reset && sleep 10 && curl -d"${ROUTER_CONFIG}" \
-H 'Content-Type: application/json;charset=utf-8' \
http://localhost:8080/form_network
That JSON blob is found by using my browser's developer tools to snoop on the front-end to the border router. It's not pretty, but it gets me going. The wpanctl reset probably isn't needed in most cases, just in our case the NCP is "special" and doesn't seem to want to work first try.

One thing I observe now, is wpantund after commissioning, will then mysteriously "forget" the prefix. In some cases, mere minutes after assigning it. e.g.

I noticed one thing, that when we add on mesh prefix for the first time and after rebooting, the ncp persist the on mesh prefix which is labelled as origin:ncp. In this state, my coap message are not able to reach RPi and also I am not able to ping RPi.
When I again add the on mesh prefix using Web GUI, new prefix is added into on mesh prefix list with label origin:user, and I am able to receive ping and coap messages in RPi.
Can anyone help me regarding this issue.
