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.

Applying that approach alone would not establish the required result: A failed server connection triggers the documented fallback while server-issued rejections remain enforced.

That observation verifies aaa lockout recovery in a different situation, such as when an administrator enables centralized-only AAA on a remote router without a validated recovery path and loses administrative access when the WAN fails. For the reported aaa server unavailable versus reject incident at a multi-tenant facility in Dublin, the required acceptance evidence is: A failed server connection triggers the documented fallback while server-issued rejections remain enforced. This other result does not test that condition directly.

That observation verifies aaa method list not applied in a different situation, such as when the intended named login method list exists but VTY access continues to use another authentication path. For the reported aaa server unavailable versus reject incident at a multi-tenant facility in Dublin, the required acceptance evidence is: A failed server connection triggers the documented fallback while server-issued rejections remain enforced. This other result does not test that condition directly.

That observation verifies aaa server group order in a different situation, such as when a local database is used first even when the desired policy requires TACACS+ primary authentication with local fallback only on error. For the reported aaa server unavailable versus reject incident at a multi-tenant facility in Dublin, the required acceptance evidence is: A failed server connection triggers the documented fallback while server-issued rejections remain enforced. This other result does not test that condition directly.

Applying that approach alone would not establish the required result: When the preferred next hop fails, qualifying traffic uses an approved alternate route and recovers appropriately.
