Please help me to achieve the attached scenerio.
Have L3 Cisco Switch(Parent/Main) which is connected with L3 Switch-1 by Connectivity A (L2 Connectivity) and with L3 Switch-2 by Connectivity B (L2 Connectivity). Have to desing a scenrio where in case of failure of Connectivity A between Switch-1 and Parent/Main Switch,,, Traffic(L2)on Switch-1 will auto shifted on Proposed connectivity between Switch-1 & Switch-2 connected to each other with gig ports(i.e Switch-1 Traffic will flow via Switch-2 towards Parent Switch)...and Same for in case of Failure of Connectivity B, i.e Switch-2 Traffic will flow via Switch-1 towards Parent Switch. and after restoration of Connectivity A or Connectivity B traffic could again auto reverted on their actual connectivity towards Parent Switch.
Note:- New or required configs to achieve this to be done only on Switch-1 & Switch-2.
