GRE over IPSec Site-to-Site VPNs w/Crypto Maps: IKEv1
 
01:12:03
In this video we take a look at the configuration and application of GRE over IPSec site-to-site tunnels between Cisco routers. Throughout this video we compare and contrast the "crypto map" approach to the "SVTI" approach and some of the background of crytpo maps. We also configure OSPF as our dynamic routing protocol of choice over our point-to-point GRE tunnel. Hope you enjoy!!!

IPSec Site-to-Site VPNs w/Static Virtual Tunnel Interfaces (SVTI): IKEv1 & IKEv2
 
02:36:29
The following video tutorial takes a deep dive into Static Virtual Tunnel Interface (SVTI) interfaces along with both IKEv1 and IKEv2. We explore all the similarities and differences between the configuration and operation of SVTIs with IKEv1 and IKEv2. The IKEv1 scenario connects two offices together over the Internet and the IKEv2 scenario connects up two offices over an MPLS L3 VPN architecture. Thanks to some typos we also get to troubleshoot what happens when you use a route-map with the wrong name, what happens when a route is learned via eBGP and you want it to be learned via EIGRP (AD concerns!), and when you enter in IP addresses wrong (good troubleshooting)! In each scenario the configuration for either EIGRP or OSPF is done so you can see how to run either routing protocol over your SVTI. The next video will show the same thing, but with crypto-maps! Enjoy!

Improving GRE stability | VPN Tunnels Part 3
 
07:43
Improving GRE stability | VPN Tunnels Part 3 Once you’ve built your GRE tunnel, you need to make sure it is stable. One of the potential issues that you may face is called Recursive Routing. This can cause your tunnel to flap repeatedly. Recursive Routing occurs when underlay routes are incorrectly advertised into the overlay. This can be worse when little attention is paid to LPM (Longest Prefix Match), the route metric, and the administrative distance. Another concern is the stateless nature of the tunnel. This can result in traffic being blackholed. We can use keepalives (heartbeats), as well as tuning the source and destination interfaces, in order to resolve this issue. There is a catch though. Keepalives do not work with route-based IPSec encryption. Neither does BFD for that matter! Some valid work arounds include using crypto-maps (policy-based encryption), using routing protocols, or using IP SLA with an EEM script. Part 1: How GRE Works - See the encapsulation process, as a packet moves from one side of the network to another Part 2: GRE Encryption with IPSec - GRE is not encrypted by default! See the basics of IPSec, and how we can use it with GRE tunnels Part 3: Improving GRE Stability - There are a few pitfalls to watch out for, including recursive routing. See some of the best practices that you can apply to make your tunnel stable For more information, have a look at https://networkdirection.net/Advanced+GRE Anatomy of GRE Tunnels (by ‘Sarah’): https://learningnetwork.cisco.com/blogs/vip-perspectives/2017/03/14/anatomy-of-gre-tunnels How to Detect IPSec GRE Tunnel Status: https://learningnetwork.cisco.com/message/590257#590257 This video is useful for Cisco #CCNA and #CCNP certifications 🌏 https://www.youtube.com/c/networkdirection 🌏 https://twitter.com/NetwrkDirection 🌏 https://www.patreon.com/NetworkDirection 🌏 https://www.facebook.com/networkdirection 🌏 https://www.networkdirection.net 🌏 https://www.patreon.com/NetworkDirection

Static Cisco VTI VPN with FortiGate 5.x Guide
 
10:45
In this short video I show a brief overview of the step by step requirements to create a VPN between a Cisco IOS using VTI and FortiGate 5.2.x track using 0.0.0.0/0.0.0.0 Quick mode selectors (Single P2) Reason to configure your Cisco with this type of VPN: • Simplifies management---Customers can use the Cisco IOS® Software virtual tunnel constructs to configure an IPSec virtual tunnel interface, thus simplifying VPN configuration complexity, which translates into reduced costs because the need for local IT support is minimized. In addition, existing management applications that can monitor interfaces can be used for monitoring purposes. • Supports multicast encryption---Customers can use the Cisco IOS Software IPSec VTIs to transfer the multicast traffic, control traffic, or data traffic---for example, many voice and video applications---from one site to another securely. • Provides a routable interface---Cisco IOS Software IPSec VTIs can support all types of IP routing protocols. Customers can use these VTI capabilities to connect larger office environments---for example, a branch office, complete with a private branch exchange (PBX) extension. • Improves scaling---IPSec VTIs need fewer established security associations to cover different types of traffic, both unicast and multicast, thus enabling improved scaling. • Offers flexibility in defining features---An IPSec VTI is an encapsulation within its own interface. This offers flexibility of defining features to run on either the physical or the IPSec interface.

GRE Encryption with IPSec | VPN Tunnels Part 2
 
09:20
GRE Encryption with IPSec | VPN Tunnels Part 2 GRE tunnels do not have any native encryption! Fortunately, you can add IPSec encryption in transport mode to your tunnel. First, we’ll have a quick look at how IPSec works. IPSec uses two security tunnels (called phase-1 and phase-2) for authentication, cipher and hash proposal, and session key exchange. Some of the protocols used in this process include ESP (Encapsulating Security Payload), IKE (Internet Key Exchange), ISAKMP, AH (Authentication Header), and the Diffie-Hellman algorithm. Once both sides agree on how these protocols will work, they will have built an SA (Security Association) If you have NAT in your network, IPSec can detect and work around it with NAT-T Try it yourself in the lab! https://networkdirection.net/labsandquizzes/labs/lab-gre-tunnels/ Part 1: How GRE Works - See the encapsulation process, as a packet moves from one side of the network to another Part 2: GRE Encryption with IPSec - GRE is not encrypted by default! See the basics of IPSec, and how we can use it with GRE tunnels Part 3: Improving GRE Stability - There are a few pitfalls to watch out for, including recursive routing.

IPsec VPN Tunnel
 
26:46
Pre-setup: Usually this is the perimeter router so allow the firewall. Optional access-list acl permit udp source wildcard destination wildcard eq isakmp access-list acl permit esp source wildcard destination wildcard access-list acl permit ahp source wildcard destination wildcard You need to enable to securityk9 technology-package Router(config)#license boot module c2900 technology-package securityk9 Router(config)#reload Task 1: Configure the ISAKMP policy for IKE Phase 1 There are seven default isakmp policies. The most secure is the default. We will configure our own. You can remember this by HAGLE. Hash, Authentication, Group (DH), Lifetime, Encryption. Router(config)#crypto isakmp policy 1 Router(config-isakmp)#hash sha Router(config-isakmp)#authentication pre-share Router(config-isakmp)#group 5 Router(config-isakmp)#lifetime 3600 Router(config-isakmp)#encryption aes 256 We used a pre-shared key for authentication so we need to specify the password for the first phase. Router(config)#crypto isakmp key derpyisbestpony address 208.77.5.1 show crypto isakmp policy Task 2: Configure the IPsec Policy for IKE Phase 2 Configure the encryption and hashing algorithms that you will use for the data sent thought the IPsec tunnel. Hence the transform. Router(config)#crypto ipsec transform-set transform_name esp-aes esp-sha-hmac Task 3: Configure ACL to define interesting traffic Even though the tunnel is setup it doesn’t exist yet. Interesting traffic must be detected before IKE Phase 1 negotiations can begin. Allow the local lan to the remote lan. Router(config)#access-list 101 permit ip 192.168.0.0 0.0.0.255 10.0.0.0 0.0.0.255 show crypto isakmp sa Task 4: Configure a Crypto Map for the IPsec Policy Now that interesting traffic is defined and an IPsec transform set is configured, you need to bind them together with a crypto map. Rotuer(config)# crypto map map_name seq_num ipsec-isakmp What traffic will be interesting? The access-list we made before. Router(config-crypto-map)#match address 101 The transform-set we created earlier for the IPsec tunnel. Router(config-crypto-map)# set transform-set transform_name The peer router you’re connecting to. Router(config-crypto-map)#set peer 172.30.2.2 You need to set the type of DH you want to use. Router(config-crypto-map)#set pfs group5 How long these setting will last before it’s renegotiated Router(config-crypto-map)#set security-association lifetime seconds 900 Task 5: Apply the IPsec Policy Apply the crypto map to the interface. Router(config)#interface serial0/0/0 Router(config-if)#crypto map map_name show crypto map derpy: http://th03.deviantart.net/fs71/PRE/f/2012/302/6/1/derpy_hooves_by_freak0uo-d5jedxp.png twilight: http://fc03.deviantart.net/fs70/i/2012/226/e/5/twilight_sparkle_vector_by_ikillyou121-d56s0vc.png

LabMinutes# SEC0020 - Cisco Router Easy VPN (EZVPN) with Dynamic Virtual Tunnel Interface (DVTI)
 
27:18
more Cisco VPN Video at http://www.labminutes.com/video/sec/vpn The video desmonstrates the configuration of Easy VPN (EZVPN) using Dynamic Virtual Tunnel Interface (DVTI) on Cisco routers and explains its benefit over the conventional EZVPN with 'crypto map' or tunnel interface with GRE. Here we introduce the concept of Virtual-Template. The second half of the video shows example of additional features that you can implement with VTI using QoS and multicasting. Topic includes - DVTI with EZVPN - Interface Virtual-Template - QoS on DVTI - Multicast on DVIT
