Validating a Route
To validate a route from ASn, ASn+1 needs:
- 1 address attestation from each organization owning an address block(s) in the NLRI
- 1 address allocation certificate from each organization owning address blocks in the NLRI
- 1 route attestation from every AS along the path (AS1 to ASn), where the route attestation for ASk specifies the NLRI and the path up to that point (AS1 through ASk+1)
- 1 certificate for each AS or router along the path (AS1 to ASn) to use to check signatures on the route attestations
- and, of course, all the relevant CRLs must have been checked
