Hi Jonathan Thanks for your help. I edited the file ../ot-br-posix/third_party/openthread/repo/examples/common-switches.mk (see file attached) and set

OpenThread's `macfilter ` feature. - Build Configuration: src/core/config/mac.h - CLI: macfilter command With macfilter, you can whitelist IEEE 802.15.4 extended addresses

1: macfilter addr clear >> 1: macfilter addr disable >> 1: childtimeout 100 >> ../../../build/x86_64-unknown-linux-gnu/examples/apps/cli/ot-cli-ftd

So, I did some testing. I used posix implementation from current OpenThread master, running just 1 ot-cli-ftd being leader. I modified the MLE

Hi Jonathan, I attached the requested log + sniffer trace. *For info in my test:* LEADER addr = 66a591acce126c77 ROUTER1 addr = 369cbb9341337dc3 REED
