Question 220
Two R82 gateways are planned to protect IPv6 networks over Site-to-Site IPsec. A legacy design document requests IKEv1 aggressive mode, although the protected flows use IPv6 on both ends. What IKE choice is supported for IPv6 VPN negotiation?
Explanation
Correct Answer
Use IKEv2 for IPv6 Site-to-Site VPN traffic; R82 IPv6 protection does not support IKEv1 aggressive mode.
Incorrect Answers
General IKE troubleshooting does not change the protocol support requirement for IPv6 VPNs.
Matching pre-shared keys can authenticate IKE but cannot make IKEv1 aggressive mode supported for IPv6.
Local Link Selection configuration does not enable an unsupported IKE generation for IPv6.
