Hi @ReneMolenaar and @lagapidis , I have tested this with my lab.Service VPN is working fine.But I have some confusion because in my main dashboard it said partial wan connectivity.when I dig deeper I found that BFD sessions between two colors are down. ![image](https://cdn-forum.networklessons.com/uploads/default/original/2X/3/301834d8be0e9ad3fe1419002d5e8097e13a26e4.png) As far as I know WAN edge routers try to form overlay tunnels to every received TLOC from a different site using every available color.So can you please help me to understand this issue.Your help is highly appriciated Update 🙂 Actually after I configure default route from both vEdge routers Full WAN connectivity obtained. ![image](https://cdn-forum.networklessons.com/uploads/default/original/2X/2/2f26f57b2ab6f0e408a6b1168e8f88d3ed35006c.png) But If I create static routes to obtain the same connectivity it is not working… For a example : If create following summery routes insted of defult route BFD is down between two colors. ip route 10.65.0.0/16 10.65.91.100 ip route 10.65.0.0/16 10.65.92.100 Can you please explain what is the logic here .. --- _[View the full topic](https://forum.networklessons.com/t/cisco-sd-wan-service-vpn/14955)._
