Disable route check in SD-WAN rule

Another alternative to using SD-WAN as a default route globally is to disable route check on per-rule basis.

For each SD-WAN rule where a valid route to the destination is not expected to exist (such as the RIA rules), you can enable the two advanced options gateway and default that are mentioned in the beginning of this chapter:

This instructs the SD-WAN rule to bypass any route check and forward the traffic unconditionally through the member selected by the configured strategy. Hence, if H1_MPLS is selected in our RIA example, the Internet traffic will be backhauled to the Hub, even if no default route is learned through H1_MPLS.
