CCNA Routing and Switching (legacy) — Question 157

Which two statements about IPv6 and routing protocols are true? (Choose two.)

Answer options

• A. EIGRPv3 was developed to support IPv6 routing.
• B. OSPFv3 was developed to support IPv6 routing.
• C. Loopback addresses are used to form routing adjacencies.
• D. EIGRP, OSPF, and BGP are the only routing protocols that support IPv6.
• E. Link-local addresses are used to form routing adjacencies.

Correct answer: B, E

Explanation

The correct answers are B and E because OSPFv3 is specifically designed to support IPv6, and link-local addresses are indeed used for forming routing adjacencies in an IPv6 environment. Options A and D are incorrect as EIGRPv3 does not exist, and other protocols besides EIGRP, OSPF, and BGP also support IPv6.
