What is Dmvpn and how does it work?

Summary

What is the difference between VPN and DMVPN?

Understanding DMVPN: While a VPN acts as a connector between remote sites and HQ, or between different branches, the DMVPN creates a mesh VPN protocol that can be applied selectively to connections being utilized in the business already. Each different site (or spoke) can connect to one another securely.

What is DMVPN for dummies?

DMVPN (Dynamic Multipoint VPN) is a routing technique we can use to build a VPN network with multiple sites without having to statically configure all devices. It’s a “hub and spoke” network where the spokes will be able to communicate with each other directly without having to go through the hub.

What are the disadvantages of DMVPN?

DMVPN hub-and-spoke topology designs have the following disadvantages: No support for non-IP protocols. IGP routing peers tend to limit the design scalability. No interoperability with non-Cisco IOS routers.

What is the difference between GRE and DMVPN?

GRE requires statically defined endpoints, which makes dynamic IP’s impossible. That’s where DMVPN comes in. DMVPN allows us to configure a single tunnel at the hub site. Each spoke site can then simply join the DMVPN network, with minimal effort, and optionally with dynamic IP addresses.

What is the benefit of DMVPN?

DMVPN Benefits: Reduces the cost of secure communications and connections between branches by integrating VPN with communication practices. Allows for easier branch-to-branch communications and connections through a centralized system. Reduces the likelihood of downtime by securing routing with IPsec technology.

Is DMVPN still being used?

DMVPN is still used in many networks. It requires the network administrator to understand and configure IPsec and dynamic routing protocol such as EIGRP.

What are the 3 phases of DMVPN?

DMVPN Phases: DMVPN phase 1 2 3DMVPN Phase 1: All traffic flows through the hub. The hub is used in the network’s control and data plane paths.DMVPN Phase 2: Allows spoke-to-spoke tunnels. Spoke-to-spoke communication does not need the hub in the actual data plane.DMVPN Phase 3: Improves scalability of Phase 2.

What is the alternative to DMVPN?

A popular alternative to DMVPN is FlexVPN.
