Huawei Certified ICT Expert – Data Center Network (HCIE-DCN) — Question 19

In BGP/MPLS IP VPN, the OSPF multi-instance process uses the DN bit to prevent Type5 LSA loops.

Answer options

• A. TRUE
• B. FALSE

Correct answer: B

Explanation

The correct answer is B because the DN bit is not used in OSPF multi-instance processes to prevent Type5 LSA loops. Instead, Type5 LSAs are managed through other mechanisms in OSPF to avoid routing loops. Thus, stating that the DN bit serves this purpose is incorrect.
