The openthread protocol stack ot1.3 is directly used to enable the function of the border router, and the external host cannot be pinged.

Using the openthread protocol stack, when testing ot1.3, enable

"-DOPENTHREAD_CONFIG_BACKBONE_ROUTER_ENABLE=1"

"-DOPENTHREAD_CONFIG_NAT64_BORDER_ROUTING_ENABLE=1"

"-DOPENTHREAD_CONFIG_NAT64_TRANSLATOR_ENABLE=1"

"-DOPENTHREAD_CONFIG_MAC_CSL_RECEIVER_ENABLE=1"

"-DOPENTHREAD_CONFIG_DUA_ENABLE=1"

"-DOPENTHREAD_CONFIG_MLR_ENABLE=1"

Enter the br enable command, and the prompt is error 13: invalidstat. After viewing the program, it is found that BR has not been initialized. Which cli is used for BR initialization.

The default OpenThread Border Router build should enable IPv6 routing. See the ot-br-posix CMake file for OpenThread: https://github.com/openthread/ot-br-posix/blob/main/third_party/openthread/CMakeLists.txt

I suggest taking a look at the Thread Border Router - Bidirectional IPv6 Connectivity and DNS-Based Service Discovery code lab if you want to setup and play with Thread 1.3 features.
