R2 begins sending ICMP traffic to R4, but it currently only has a GRE tunnel open to R1. The first two ICMP requests (packets #1 and #4) are routed through R1 while R2 sends an NHRP request to R1 for R4's spoke address. Once a GRE tunnel is dynamically built between spoke routers R2 and R4, R2 begins routing the ICMP traffic directly to R4. Capture perspective from the R2-R5 link.
