Hi,Chenyin
Yes, I want to stop the forwarding of a certain port in the CAN2CAN operation. Normally, after receiving the 0x123 message on BCAN1, it is directly routed to BCAN2 for transmission. Now (assuming there is such a switch), if the routing is turned off, BCAN1 stops forwarding the 0x123 message, but BCAN1 can still receive other messages normally. Simply turning off its routing function is sufficient.
