Its responsibility is in setting up security associations that allow two parties ikev1 vs ikev2 send data securely. IKE was introduced in and was later superseded by version 2 roughly 7 years later. Freeing up bandwidth is always a good thing as the extra bandwidth can be used for the transmission of data.

Computers need a method for secure recognition between devices - the purpose of which is to be able to trust each other, before further communications take place. One way to think about this is to consider your front door. It unlocks using a unique key. There are many other keys out there, but only yours will unlock the door. In the same way IKEv ensures that when one device connects to another, they really are trustworthy. It will then establish how to securely communicate.

However, the two protocols function significantlly differently in terms of how IPsec tunnels are built, and this guide is intended to illustrate these differences, and when one can be used over the other. However, since IKEv1 as a protocol restricts a security association to a single source and destination, this introduces overhead and scale concerns. Each pair of subnets in a VPN requires at least two SAs for bidirectional communication, which means the required number grows in a non-linear fashion as more subnets are added. This may also cause issues with certain cloud service providers, who have limits on how many concurrent SAs can be established at a time e. The following example visualizes how the security associations would logically appear between an MX appliance and a 3rd-party peer that each have two subnets participating in a VPN with IKEv Note however, that since SAs are keyed on demand i. This means a single pair of SAs can provide full connectivity between two peers, regardless of how many subnets are involved, as the following illustration shows:. As a result, IKEv2 can allow us to scale up significantly higher than IKEv1, since there's no need to keep keying additional SAs as more subnets are added. Cisco ASAs. Such implementations generally respond to requests to key an IPsec SA by only using a single pair of subnets. Such debugging is only possible on Meraki devices by contacting Support, and requires tearing down and re-establishing the tunnels in question. The following excerpt shows part of a successful IKEv2 exchange between two devices, forming a VPN between the subnets Given that there are four different Traffic Selector payloads in this single packet, the MX is attempting to establish a single security association that covers all 4 of the involved subnets, and the peer acknowledges this by sending a response that includes all 4 as well. The net result of this exchange is a working pair of SAs that allows bi-directional connectivity between all of the involved subnets.

In the same way IKEv ensures that when one device connects to another, they really are trustworthy. It will then establish how to securely communicate. This standard protocol is designed to establish secure, and authenticated communication between two devices on the internet. It has gone through a few revisions at this point, which is why it also gets referred to as IKEv1, or IKEv2 which designates the appropriate revision, the latest naturally being IKEv2.

Internet Key Exchange IKE is a protocol used to set up a secured communication channel between two networks. To establish a secured channel, the two communicating parties need to create a Security Association SA between each other through the use of Internet Protocol Security IPsec. IKEv2, the newest version of this protocol, offered several improvements that make it much more secure and easier to implement than previous versions. The new version of IPsec, IKEv2, is much more secure and provides better security for companies and organizations.

One cited benefit is that IKEv2 uses less bandwidth than its predecessor - a desirable benefit to maximize data transfer with less overhead.
