Dear RYU Team,

I am developing some rerouting scenario when there is some node failure. I
have attached my testing topology testbed. RYU controller is at the gateway
1 and raspi 1 and raspi 2 are directly connected to gateway 1. raspi 3 is
connected to raspi 2 and raspi 1. The primary route for raspi3 to gateway 1
is raspi 3 - raspi 1 - gateway 1. what i am trying to do is when raspi 1 is
down, RYU controller want to assign the flow rules to raspi 2 to relay the
data from raspi 3 to gateway 1. So that raspi 3 can be connected to the
gateway 1 through the route of raspi 3 - raspi 2 - gateway 1. But I cannot
assign the flow rules to raspi 2 when raspi 1 is failed. Is there any way
to assign the flow rules to other node when the node is failure. Any
suggestions are warmly welcomed.

Best Regards,
