Looking for input
Is it possible to have Two Tunnels from each Spoke to HeadQuarter(hub_site) with one tunnel Active and another tunnel inactive.
It would be GRE over IPSEC ( Eigrp or OSPF )
Spoke_1_Tunnel#1==============HQ_Hub1 ( Active Tunnel )
Spoke_1_Tunnel#2==============HQ_Hub2 ( Inactive Tunnel )
If Link at HQ for Hub#1 is down then Tunnel#2 becomes active and all traffic flows on this tunnel.
