Need your suggestion to configure the scenerio attached in diagram.
---> Parent Switch-A & Parent Switch-B are connected with Switch-1 & Switch-2 respectively(Both are L2 connectivity).
---> There are some other access connectivities extended from parent switches A & B apart from connectivities shown in diagram.
We are looking for below scenerio :-
1) If the connectivity between Parent Switch-A & Switch-1 fails, the traffic from switch-1 autoshifted or follow other uplink path by proposed connecivity betwen Switch-1 & witch-2 i.e Switch -1 traffic---> Swicth-2 --> Parent Switch-B.
2) Same is applicable for reverse case. i.e if connectivity between Parent Switch-B & Switch-2 fails, all the traffic autoshifted to proposed connectivity between Switch-1 & Switch-2. ie. Switch-2 Traffic --> Switch-1--> Parent Switch-A.
3) Kindly note we are avoiding any config changes on both parent switches as heavy traffic running on both and as mentioned other access L2 connectivity running via both (on some access connectivities same Vlans are running as on this proposed connectivity).
