Duplicate Packet recieved between source to destination
I have a redundant network at our client.I have attached actual connectivity diagram of network. We are using Cisco 6505 switch(L3 switch) and Cisco 3750G (as a L2 switch) in network.
I have two NIC cards at each PCs with Linux OS.We made BONDs on each PC( means two NIC cards hold one IP address which actually shows in Bond).In a PC one NIC cards works as Active and other one as a Standby.
Its working fine when there is no change in network connectivity in network as per diagram attached.It means both active NIC cards work fine when we PING from Source PC to Destination PC.
But if we remove Patch cord of Active Link from Source PC and try to ping from Source PC to Destination PC, every time same packet (duplicate packet) recieved from destination PC on source pc.
1) Why it is happening?
2) How can i resolve duplicacy of packet in this scenario?
