On receiving the redirect, Spoke1 initiates a resolution request for Host2 over the point-to-point tunnel interface (the same interface over which it received the redirect). The resolution request traverses the routed path (Spoke1-hub-spoke2). On receiving the resolution request, Spoke2 determines that it is the exit point and needs to respond to the resolution request. https://www.cisco.com/en/US/docs/ios-xml/ios/sec_conn_ike2vpn/configuration/15-2mt/sec-flex-spoke.html
