Hello All,
I am trying to send a ethernet packet to particular multicast address, for e.g 91:e0:f0:00:fe:00 , but i receive two packets in receiving end. Issue happens when both eno2 and eno3 interface is UP. Hardware used is LS1028ardb.
Below is the connection : eno0 --> swp0 , swp1 -->PC
Now packet is sent on eno0 (for destination addr 91:e0:f0:00:fe:00), PC receives two instance of same packet
Bridge is construction using below command:
ifconfig eno0 up
ifconfig eno2 up
ifconfig eno3 up
ip link add name switch type bridge;
ip link set switch up;
ip link set swp0 master switch && ip link set swp0 up;
ip link set swp1 master switch && ip link set swp1 up;
ip link set swp2 master switch && ip link set swp2 up;
ip link set swp3 master switch && ip link set swp3 up;
ip link set swp4 master switch && ip link set swp4 up;
ip link set swp5 master switch && ip link set swp5 up
I need both the interface eno3 and eno2 to be UP. eno2 is required for L2 forwarding and eno3 for running ptp4l on switch ports.
Another observation is there will be no entry created in FDB table for this multicast destination address, so may be it is flooding to all ports, leading in duplication of packets.
If i run tsntool cbstreamidset command, FDB entry is getting created.
Please suggest how to address this problem. Is this a valid behavior to receive duplicated packet? If so what could be possible solutions to avoid this duplication behavior. Thanks.
