CCDE: Cisco Certified Design Expert (Practical) — Question 17

Which two mechanisms avoid suboptimal routing in a network with dynamic mutual redistribution between multiple OSPFv2 and EIGRP boundaries? (Choose two.)

Answer options

• A. AD manipulation
• B. matching OSPF external routes
• C. route filtering
• D. matching EIGRP process ID
• E. route tagging

Correct answer: C, E

Explanation

Route filtering helps in controlling which routes are redistributed between OSPFv2 and EIGRP, thereby avoiding suboptimal paths. Route tagging assists in identifying and managing routes during redistribution, ensuring that the most efficient routes are preferred. The other options, while related to routing, do not specifically address the issue of avoiding suboptimal routing in this context.
