That observation verifies eigrp stub leaf in a different situation, such as when a remote branch does not transit traffic yet its router receives network-wide EIGRP query requests for unrelated destinations. For the reported eigrp passive-interface incident at a logistics WAN in Rotterdam, the required acceptance evidence is: Hello exchanges resume on the routing link without creating unexpected user-LAN adjacencies. This other result does not test that condition directly.

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 an energy services network in Calgary, 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.

That observation verifies dmvpn nhrp network id mismatch in a different situation, such as when the hub and spoke use different NHRP network identifiers despite otherwise consistent tunnel addressing.

This other result does not test that condition directly.
