Subject: lossless traffic in ovs fast-failover group + bfd


Hi

I am trying to setup fast-failover group + BFD in ovs switch. Its working fine as well in following topology.

h1_S1___S2_h2

        |_S3_|


Though I am having query on traffic loss between short time of port on remote switch (s2) going down to that is being learnt by S1 using BFD. I see in ping 3-4 packets are lost in this transition.

Is there anyway we can buffer this packet loss and resend it to new path again (s3) before actual path switching happens?


Thanks,

Vrushali
