SD-WAN Appliances at the DC and Branch sites should be running latest release version.
End-to-End IP connectivity should be configured and working fine.
OSPF is enabled on all the sites.

As shown in the illustration above, DC MCN is deployed in one-arm topology. When DC site is up, one-arm router forwards
all traffic from local LAN to other sites, such as the Branch's local LAN whose destination IP address is within same subnet
to the SD-WAN first, then SD-WAN appliance wraps all packets and sends it to the router with all the packets destination
IP address in the Branch Virtual IP address. The router then forwards those packets to WAN.
When the DC site is down, router forwards all traffic from local LAN to other sites (branch site's local LAN, destination IP is
within subnet) to WAN directly, and not to the SD-WAN appliance.
OSPF Type5 to Type1 Deployment in MPLS Network
The following deployment mode is provided to avoid loop formation in an MPLS network configured using SD-WAN
appliances. The illustration below describes the standard MPLS network implementation.
