I would like to ask for any suggestion for automatic failover of our network.
IPsec>>>Core2>> L2Switch>>>L2switch>>> Two Core1 VSS switches>>> MPLS router.
Core2 do not have a connection to the MPLS directly, and is only connected via Core1. We would like to setup automatic failover of Core2 network to IPsec once the Core1 network is down. IP SLA is not possible due to IOS of Core2 switch. Appreciate for any help.
