(note this all seems pretty far out of rrg though) So let me answer your question just in the context of a Topology Aggregating Routing Architecture: Each TARA-router would realize that its geopatch is partitioned by receiving BGP-UPDATE's containing TARA-links of some upper zoom into the own geopatch which it wasn't able to produce itself. Loopfree, minimally detouring routes via neighboring geopatches can be determined and can be enforced for being taken. Heiner
