However, the tunnel does not come up:. In the output above we can see that we look for the R4-Profile, we are then told that the profile has no keyring, it must be the ISAKMP profile that the logs are referring to, as that is the only thing we are currently debugging. It does not find a keyring, but it does find a local preshared key. So, it looks like we need to add a keyring, which will contain our pre-shared key:. We did not need to add one for the connection between R1 and R3, as the existing one for the Easy VPN used the loopback address.

CCIE Why did you use Virtual-template for the third tunnel? It could work without it, just set isakmp-profile under ipsec profile. How does it work, when not defined? Could you please explain that in more detail? I wonder, why Cisco did this so complicated and unintuitive….

I am a bit busy with ACI at the moment but will be returning to the world of security in a while. To give you a quick answer… things just seemed to work better like that. If no virtual template is required then great, but if the question says to ue a VT?? Hence playing around… I will try and explain it better when I have more time.

IPsec Virtual Tunnel Interfaces IPsec virtual tunnel interfaces VTIs provide a routable interface type for terminating IPsec tunnels and an easy way to define protection between sites to form an overlay network. Note Security threats, as well as the cryptographic technologies to help protect against them, are constantly changing.

Tunnel Protection Do not configure the shared keyword when using the tunnel mode ipsec ipv4 command for IPsec IPv4 mode. Traceroute The traceroute function with crypto offload on VTIs is not supported. Static Virtual Tunnel Interfaces SVTI configurations can be used for site-to-site connectivity in which a tunnel provides always-on access between two sites.

The figure below illustrates how a SVTI is used. Figure 1. Figure 2. Router 1 authenticates User 1. Figure 3. Packet Flow into the IPsec Tunnel After packets arrive on the inside interface, the forwarding engine switches the packets to the VTI, where they are encrypted. Figure 4.

IPsec configuration. QoS configuration. EasyVPN configuration. Recommended cryptographic algorithms. By applying it to the tunnel interface, you are are implicitly saying that the crypto peer is the tunnel destination and that the traffic that should be encrypted is any traffic that uses the tunnel. The same profile can be applied to multiple tunnels as long as you want them to use the same transform set.

The full configuration now looks like this:. A router that has multiple tunnels obviously benefits more from crypto profiles since maintaining multiple crypto map entries and ACLs gives you opportunities to make mistakes.

I apologize for the Transformers reference It completely replaces the previous crypto map, which can be removed, including the ACLs. To use the crypto profile, you apply it directly to the tunnel interface:!

This includes things like the keepalive, identities, authentication xauth etc. The VPN configuration is complete but there is one thing left to do. We use IP unnumbered which takes the IP address from the loopback interface 1. We only need to specify the pre-shared key for the hub. Explained As Simple As Possible. Full Access to our Lessons. More Lessons Added Every Week! Tags: IPSec , Security. It is true that IPsec alone does not support multicast.

GRE supports multicast so this would solve the problem. Ask a question or join the discussion by visiting our Community Forum. Skip to content Search for: Search. Lesson Contents. Configurations Want to take a look for yourself? Here you will find the startup configuration of each device. I am using a different pre-shared key for each peer. This works well when each spoke router has a static public IP address.

If you have dynamic public IP addresses on your spoke routers then you can also use a single pre-shared key for all your peers. If you want this, use pre-shared-key address 0. Could you please explain that in more detail?

I wonder, why Cisco did this so complicated and unintuitive…. I am a bit busy with ACI at the moment but will be returning to the world of security in a while.
