<div dir="ltr">Hi everyone, I have four switches connected in a loop, each switch has two hosts connected with it. My requirement is to maintain flow in one direction only i.e., echo request and echo reply after issuing a ping command should take different routes. If I want to ping h3(connected to s2) from h1(connected to s1), destination(h3 @ s2) is unreachable, In this case controller should tell s1 to forward packet to port connected to s2. My question is how would controller know which s1 port is connected to s2 and if I broadcast the packet it remains in a loop and never reaches at its destination. Thank you!<br clear="all">
