We'll be basing our conditional default routes on the presence of a core route from at least one of our three service providers. The default-originate route-map must match on a route explicitly present in the routing table. Unfortunately, AS path and next-hop information are not valid parameters in this scenario. We've chosen two core routes from each provider, routes which are integral to their backbones and extremely unlikely to disappear from BGP announcements: Mzima: 67.201.0.0/18 72.37.128.0/18 GNI: 64.127/96.0/19 64.147.160.0/19 Level3: 4.0.0.0/8 62.67.0.0/16 As long as we are receiving one of these routes (from *any* source), we assume we still have a viable connection to the internet at large. The router will inject a default route into our internal OSPF areas as long as any of these provider routes are being learned via BGP.
