Hi,I suspect anti spoofing problem.You can enable RPF with the following configuration command:Firewall(config)# ip verify reverse-path interface if_name
Hi,I can suggest to check on the switch port VLANs.The both interfaces should be in same VLAN.and check the fail over configurations again like VRRP IP ( is it valid IP in th subnet) and other settings.Hope it might help.Cheers
