It can happen at the ISP end at spoke2 or at any firewall in path between spoke2 router and spoke1 router. After they allow ESP (IP Protocol 50), spoke1 and spoke2 both show encaps and decaps counters increment. If they are close to the configured lifetimes (default is 24 hrs for ISAKMP and 1 hour for IPsec), then that means these SAs have been recently negotiated.
