Question 500
After a new ISP circuit is added, traffic in an R82 VPN community unexpectedly negotiates from a backup WAN interface. The peer has pinned the primary public address. Routing is valid and IKE proposals match. The operator must distinguish this from a separate requirement to choose the outgoing gateway address for VPN traffic. Which supported change follows from the actual evidence rather than that alternative hypothesis?
Explanation
Correct Answer
Link Selection determines the address advertised and route used. This directly addresses the documented incident evidence.
Incorrect Answers
Changing source Hide NAT does not establish the VPN gateway public-address choice reported by the remote peer.
VPN Link Selection can share VPN traffic across available links, yet that applies to define how VPN traffic is distributed across multiple usable links rather than the observed issue.
Enhanced Link Selection supports cloud IPsec redundancy without proprietary RDP, with DAIP and platform limits; this does not resolve the observed condition.
