Will a VPN Connection Be Re-established After Its Configuration Is Modified?

A VPN connection consists of local subnets, customer subnets, customer gateway, pre-shared keys (PSKs), IKE negotiation policy, and IPsec negotiation policy. A VPN connection is modified if any of the following happens:

If the local and customer subnets are modified, the connection ID will remain unchanged. If not all subnets are updated, the established tunnel between subnets will not be re-established.
If the IP address of the customer gateway is changed, the connection ID will remain unchanged, but the VPN connection will be re-established.
If only the PSKs are changed, the connection ID and status will remain unchanged. The PSK will be checked again during renegotiation. If the PSKs do not match, the renegotiation fails.
If a negotiation policy is modified (PSK verification is required), the connection ID will be changed and the connection needs to be re-established.
