Company A recently acquired Company B and the network infrastructures are being merged. Both organizations used non-overlapping globally unique network addressing but different Interior Gateway Protocols (IGPs). Initially, multiple WAN links will connect the two organizations. Company A will maintain its core routing protocol, and Company B's routing protocol will be the edge routing protocol. Two-way redistribution will be used to ensure full network routing capability.
What additional routing configuration should be performed to prevent routing loops and suboptimal routing?
- A: Manually configure static routes.
- B: Manually configure default routes.
- C: Manually adjust the administrative distances.
- D: Manually adjust the local preference attribute.
