My client has all their spokes configured with a basic topology: 1 MX + 2 ISP routers.
I recently did a soft failure test by disconnecting the WAN link of the primary ISP router.
What I noticed is the converge time of VPN traffic is much faster than Internet traffic. I tested with 3 sites and saw the same behavior: VPN traffic was back after 1-2 minutes but we should always wait for around 4-5 minutes to see our "ping 220.127.116.11" works again. I understood that in case of soft failure, the convergence time can be up to 5 minutes, what I do not understand is why the difference between VPN traffic and Internet traffic.
Could you help me to understand what happened please?
