Fixing the Mesh-Local EID

[Nidhal Fliss]

Hello, I'm trying to fix the Mesh-local EID of one of my devices using theotIp6AddUnicastAddress and sending CoAP messages to it, however it is being filtered in the MAC layer. the error is "OT_ERROR_DESTINATION_ADDRESS_FILTERED". 

My question is, are there more steps to be observed in Fixing the devices IP6@ than just assigning a random @(I've tried various scopes to no avail) ?. If possible can you provide some practical example for this use case.

Thank you for time

Regards.

What is the exact value of the IPv6 address you are trying to configure?

You can easily test manual configuration of IPv6 addresses via the CLI as follows:

1) Configure Node 1:

> panid 0x1234

Done

> ifconfig up

Done

> thread start

Done

2) Configure Node 2:

> panid 0x1234

Done

> ifconfig up

Done

> thread start

Done

3) List IPv6 addresses on Node 2:

> ipaddr     

fdde:ad00:beef:0:0:ff:fe00:5801

fdde:ad00:beef:0:ea5e:6210:c6e0:931e

fe80:0:0:0:8c75:b363:87dd:3f67

Done

4) Configure new mesh-local IPv6 address on Node 2 and verify:

> ipaddr add fdde:ad00:beef:0::beef    

Done

> ipaddr

fdde:ad00:beef:0:0:0:0:beef

fdde:ad00:beef:0:0:ff:fe00:4400

fdde:ad00:beef:0:ea5e:6210:c6e0:931e

fe80:0:0:0:8c75:b363:87dd:3f67

Done

5) Ping manually configured address from Node 1.

> ping fdde:ad00:beef:0:0:0:0:beef

8 bytes from fdde:ad00:beef:0:0:0:0:beef: icmp_seq=1 hlim=64 time=10ms
