Abstract: In one embodiment, method includes receiving, by a first network apparatus, a first multicast message from a second network apparatus. The first multicast message includes attestation-capability information associated with the second network apparatus and an attestation token. The attestation token is for proving that the second network apparatus is in a known safe state. The method also includes determining, by the first network apparatus, that the attestation-capability information satisfies a pre-determined attestation capability requirement and determining, by the first network apparatus, that the attestation token is valid for the second network apparatus at a current time. The method further includes establishing, by the first network apparatus, an adjacency to the second network apparatus.
