Hi @RS19 

In Cisco SD-WAN the WAN Edge routers securely communicate to other WAN Edge routers using IPsec tunnels over each transport. BFD protocol is enable by default and runs over each os these tunnels, detecting loss, latency, jitter and path failures.

You can check this using the following command:

vEdge20# show bfd sessions | tab

                                SRC    DST                  SITE                                     DETECT      TX
SRC IP      DST IP       PROTO  PORT   PORT   SYSTEM IP     ID    LOCAL COLOR   COLOR         STATE  MULTIPLIER  INTERVAL  UPTIME      TRANSITIONS

Thanks. Does it means if the bfd is down, it also means IPSec is down ?

I already mention this command in your previous post' and sure SDWAN bfd use to detect peer if peer is not reachable then IPsec or GRE will be down.

Yes, BFD is used inside IPsec tunnels between all WAN Edges.
