Which option should be part of your network design to support dynamic mutual redistribution between multiple OSPFv2 and IS-IS boundaries, to avoid suboptimal routing?

Route tagging identifies the origin of a route but does not filter or restrict which routes are redistributed, leaving suboptimal routing unresolved.

Route filtering controls precisely which routes are injected into each routing domain, preventing loops and suboptimal paths that arise from mutual redistribution. Administrative policies such as setting appropriate metrics and administrative distances ensure the preferred path is taken when routes appear in both protocols. Together these mechanisms provide fine-grained control over redistribution boundaries without discarding necessary routing information.

Route aggregation reduces routing table size but does not address suboptimal routing caused by mutual redistribution across protocol boundaries.

Disabling IS-IS wide metrics removes extended metric support and reduces scalability, worsening rather than resolving suboptimal routing in large networks.
