Redistributing only internal routes without proper tagging and filtering creates redistribution feedback loops between the two OSPF processes because redistributed routes can cycle back into their source process, destabilizing routing.

Redistributing all routes from the strategic partner's OSPF process exposes unnecessary internal routing topology to the partners, violating the principle of providing only the access they require.

Redistributing only the internal data center application routes from the strategic partner OSPF process into the internal OSPF process limits partner access to exactly what is needed, satisfying the least-privilege access requirement. Applying route tags to redistributed routes allows the receiving OSPF process to identify and suppress re-advertisement of those routes back into the originating process, preventing feedback loops that would otherwise destabilize both organizations' routing domains.

Redistributing all routes into the internal OSPF and propagating all routes back to partners introduces excessive routing information and risks negatively affecting both organizations' routing designs by flooding unnecessary prefixes.
