Scenario is that
At first I put several devices have use switches connected to the sender and the receiver, the system assigned to IP is 169.254. 7.0.x.x such IP address, multicast communication is normal at this time,
When I put the switch after receiving routing LAN port, the system will be assigned to address 192.168 7.0.x.x IP address, multicast communication is not able to at this moment, to restart the entire network to normal communication,
How do you solve this problem? Because of the routers and switches and customers, we move is equipment end!
Will always have a problem is equipment end sends a multicast packets, but the upper machine to close not to receive data, later, to restart PC to receive, this time with caught tools can catch packet,!
CodePudding user response:
IP with limited points is less than 169 line, that you this equipment is for who?Need only if you don't need networking equipment between each respective why user network access,
Not directly add a small four exchange?
If you want to use 192 and Intranet through, device does not support again, it should to change procedures
CodePudding user response:
1. On the router, and don't for multicast packets forwarding operation,Routing open DHCP service, client IP addresses are bound to change, this is normal, reset the multicast service related nodes (i.e., the original poster said the resumption of entire network),
If you don't want to restart the program, it needs to support this kind of condition, when change the IP address of the node, exit to join multicast,
2. Improve the robustness of the program
