Valadating a certificate of origin asian girl dating mexican guy
A route validity state is defined by the following procedure: 1. If the set of candidate ROAs is empty, then the procedure stops with an outcome of "unknown" (or, synonymously, "not found", as used in [BGP-PFX]). If the route's origin AS can be determined and any of the set of candidate ROAs has an as ID value that matches the origin AS in the route, and the route's address prefix matches a ROAIPAddress in the ROA (where "match" is defined as where the route's address precisely matches the ROAIPAddress, or where the ROAIPAddress includes a max Length element, and the route's address prefix is a more specific prefix of the ROAIPAddress, and the route's address prefix length value is less than or equal to the ROAIPAddress max Length value), then the procedure halts with an outcome of "valid". Otherwise, the procedure halts with an outcome of "invalid".Select all valid ROAs that include a ROAIPAddress value that either matches, or is a covering aggregate of, the address prefix in the route. Within the framework of the abstract model of the operation of inter- domain routing using BGP [RFC4271], a received prefix announcement from a routing peer is compared to all announcements for this prefix received from other routing peers, and a route selection procedure is used to select the "best" route from this candidate set.A ROA provides a means of verifying that an IP address block holder has authorized a particular AS to originate routes in the inter-domain routing environment for that address block. ROAs are intended to fit within the requirements for adding security to inter-domain routing.This document describes the semantic interpretation of a ROA, with particular reference to application in inter-domain routing relating to the origination of routes, and the intended scope of the authority that is conveyed in the ROA.

In the context of route validation, it is assumed that once an address prefix is described in a ROA, then this ROA specifically encompasses all address prefixes that are more specific than that described in the ROA.
Thus, any route for a more specific address prefix than that described by any valid ROA that does not itself have a matching valid ROA can be considered "invalid".
It's validity state is considered to be "invalid" if one (or more) ROAs provide an "invalid" outcome and no ROAs provide a "valid" outcome.
Its validity state is considered to be "unknown" (or, synonymously, "not found" [BGP-PFX]) when no valid ROA can produce either a "valid" or an "invalid" validity state outcome.
