That observation verifies ip sla tracked floating default in a different situation, such as when a static primary route remains in the RIB after upstream reachability fails because it tracks interface status only.

This other result does not test that condition directly.

That observation verifies ike esp underlay filtering in a different situation, such as when a DMVPN peer can ping its hub's public interface but IKE or ESP packets are blocked by a WAN ACL. For the reported nhrp authentication mismatch incident at a provider edge operations team in Singapore, the required acceptance evidence is: NHRP registration succeeds with its intended authentication instead of disabling the protection. This other result does not test that condition directly.
