VPN Tunnel Interface (VTI) A VPN Tunnel Interface is a virtual interface on a Security Gateway that is related to a VPN tunnel and connects to a remote peer. You create a VTI on each Security Gateway that connects to the VTI on a remote peer.

It uses if_ipsec(4) from FreeBSD 11.1+ for Virtual Tunnel Interfaces (VTI) and traffic is directed using the operating system routing table.

Concern Choose One This review contains offensive material This comment violates the Acceptable Use policy. An IPsec profile contains the required security protocols and algorithms in the IPsec proposal or transform set that it references. This ensures a secure, logical communication path between two site-to-site VTI VPN peers. IPSec profile example configuration: Therefore, you must enable it for IBM Cloud Manager with OpenStack if the remote private network's VPN gateway is set up to use VTI. If the remote private network's gateway is using a policy-based configuration, you can use the standard OpenStack VPNaaS. The use of VPN Tunnel Interfaces (VTI) is based on the idea that setting up a VTI between peer Security Gateways is similar to connecting them directly. A VTI is an operating system level virtual interface that can be used as a Security Gateway to the VPN domain of the peer Security Gateway.

Therefore, you must enable it for IBM Cloud Manager with OpenStack if the remote private network's VPN gateway is set up to use VTI. If the remote private network's gateway is using a policy-based configuration, you can use the standard OpenStack VPNaaS.

Jul 14, 2020 · For the ASA which is a part of both the VPN VTI domains, and has BGP adjacency on the physical interface: When a state change is triggered due to the interface health check, the routes in the physical interface will be deleted until BGP adjacency is re-established with the new active peer.

CCIEv5 Unprotected GRE Tunnel , Protected GRE Tunnel with IPsec -VTI Body i wrote this atatched 7 pages guide during my practice for using IPsec VTI over GRE tunnels ,it’s one of the new topics added to CCIEv5 Lab exam . Route-based VPN devices use any-to-any (wildcard) traffic selectors, and let routing/forwarding tables direct traffic to different IPsec tunnels. It is typically built on router platforms where each IPsec tunnel is modeled as a network interface or VTI (virtual tunnel interface). The following diagrams highlight the two models: Policy-based VPN
