What happens when a qualified SD-WAN link gets disqualified??

Chathura_Yapa1

Assuming that we have TWO SD-WAN link A and B, According to the scenario both the WAN links get qualified. Once the session has initiated ,suddenly link A gets dis qualified leaving only link B SD-WAN link qualified ,in such a scenario what will happen to the session which was already initiated on the disqualified path.

Q1- What will happen to the session which was already initiated through Link A?

Q2-If the session get reinitiated on the link B will there be any packet loss?

Hi @CHATHURA_YAPA1,

Thank you for visiting SonicWall Community.

Please find answers to your questions below.

Q1- What will happen to the session which was already initiated through Link A?

The session needs to be reinitiated and that happens via Link B further.

Q2-If the session get reinitiated on the link B will there be any packet loss?

I would say, a very tiny interruption is observed due to the session reinitiated on Link B.

Hope this helps.

Sorry to refloat this.

In this same line, previous question

Q1- What will happen to the session which was already initiated through Link A?

The session needs to be restarted and that happens via Link B further.

New question.

Q0-Who reinitiated the connection on Link B?

We have an SD-WAN and we are noticing connection drops, every time a Link in the group becomes NOT Qualified

Thanks.
