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

L2TPv3 (Dynamic Mode - NO IPSec) - How to Video Tutorial w/GNS3 - Part I (Part II will add IPSec)
 
01:07:30
The following is a video tutorial on L2TPv3 (RFC 3931 and updated by RFC 5641) and will walk you through, step-by-step, the process of how you would extend your Layer 2 network from one location to another (in this video I simulate extending your Layer 2 network between New York and San Diego). This video demonstrates the use of the Ethernet encapsulation of the attachment circuit interface (as opposed to using the VLAN 802.1Q encapsulation method) and I also cover each step in the setup of OSPF and there is even some debugging/troubleshooting to reveal an authentication issue between the sites. Enjoy!

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.

The protocol is classified as a path vector protocol. The Border Gateway Protocol makes routing decisions based on paths, network policies, or rule-sets configured by a network administrator and is involved in making core routing decisions. BGP may be used for routing within an autonomous system. In this application it is referred to as Interior Border Gateway Protocol, Internal BGP, or iBGP. In contrast, the Internet application of the protocol may be referred to as Exterior Border Gateway Protocol, External BGP, or eBGP. BGP neighbors, called peers, are established by manual configuration between routers to create a TCP session on port 179. A BGP speaker sends 19-byte keep-alive messages every 60 seconds to maintain the connection. Among routing protocols, BGP is unique in using TCP as its transport protocol. When BGP runs between two peers in the same autonomous system (AS), it is referred to as Internal BGP (iBGP or Interior Border Gateway Protocol). When it runs between different autonomous systems, it is called External BGP (eBGP or Exterior Border Gateway Protocol). Routers on the boundary of one AS exchanging information with another AS are called border or edge routers or simply eBGP peers and are typically connected directly, while iBGP peers can be interconnected through other intermediate routers. Other deployment topologies are also possible, such as running eBGP peering inside a VPN tunnel, allowing two remote sites to exchange routing information in a secure and isolated manner. The main difference between iBGP and eBGP peering is in the way routes that were received from one peer are propagated to other peers. For instance, new routes learned from an eBGP peer are typically redistributed to all iBGP peers as well as all other eBGP peers (if transit mode is enabled on the router). However, if new routes are learned on an iBGP peering, then they are re-advertised only to all eBGP peers. These route-propagation rules effectively require that all iBGP peers inside an AS are interconnected in a full mesh. How routes are propagated can be controlled in detail via the route-maps mechanism. This mechanism consists of a set of rules. Each rule describes, for routes matching some given criteria, what action should be taken. The action could be to drop the route, or it could be to modify some attributes of the route before inserting it in the routing table.
