That observation verifies eigrp k-value disagreement in a different situation, such as when eIGRP hello packets arrive but routers refuse adjacency because composite-metric K values do not agree. For the reported bidirectional redistribution loop incident at an industrial backbone in Munich, the required acceptance evidence is: The tagged routes are not readvertised into their original domain and stable loop-free paths remain. This other result does not test that condition directly.

That observation verifies bgp remote as incorrect in a different situation, such as when a BGP peer sends an OPEN notification and rejects the relationship because the configured remote-as does not match its actual ASN.

This other result does not test that condition directly.

This other result does not test that condition directly.

That approach is relevant to aaa command authorization, such as when a user authenticates successfully but sensitive configuration commands are not checked against command-level authorization. That is a different root cause from the aaa method list not applied fault observed at a regulated enterprise in London. Applying that approach alone would not establish the required result: VTY logins follow the documented server/local decision path.

That approach is relevant to radius authentication transport, such as when a router's RADIUS server is reachable by ICMP but RADIUS requests time out because authentication and accounting UDP ports are blocked. That is a different root cause from the aaa method list not applied fault observed at a regulated enterprise in London. Applying that approach alone would not establish the required result: VTY logins follow the documented server/local decision path.

That approach is relevant to aaa accounting records, such as when management logins succeed but the audit system has no connection or command records. That is a different root cause from the aaa method list not applied fault observed at a regulated enterprise in London. Applying that approach alone would not establish the required result: VTY logins follow the documented server/local decision path.

That observation verifies aaa source interface mismatch in a different situation, such as when aAA requests leave from an unexpected source IP that the policy server does not recognize as an authorized network device. For the reported aaa method list not applied incident at a regulated enterprise in London, the required acceptance evidence is: VTY logins follow the documented server/local decision path. 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 method list not applied incident at a regulated enterprise in London, the required acceptance evidence is: VTY logins follow the documented server/local decision path. This other result does not test that condition directly.

That observation verifies aaa server unavailable versus reject in a different situation, such as when a router is configured TACACS+ then local, but an explicit reject from the active TACACS+ server is expected to trigger local fallback. For the reported aaa method list not applied incident at a regulated enterprise in London, the required acceptance evidence is: VTY logins follow the documented server/local decision path. This other result does not test that condition directly.

That approach is relevant to eigrp stub leaf, such as when a remote branch does not transit traffic yet its router receives network-wide EIGRP query requests for unrelated destinations.

Applying that approach alone would not establish the required result: The hub can advertise spoke-learned routes back out the relevant multiaccess tunnel without unstable loops.

Applying that approach alone would not establish the required result: The hub can advertise spoke-learned routes back out the relevant multiaccess tunnel without unstable loops.
