What is the difference between DMVPN and FlexVPN?
In its essence, FlexVPN is the same as DMVPN. Connections between devices are still point-to-point GRE tunnels, spoke-to-spoke connectivity is still achieved with NHRP redirect message, IOS routers even run the same NHRP code for both DMVPN and FlexVPN, which also means that both are Cisco’s proprietary technologies.
What is difference between Getvpn and FlexVPN?
GET VPN is used for site-to-site only, whereas FLEX VPN is able to work with site-to-site and Remote Access (RA VPN) deployments at once. GET VPN was designed to take advantage of the inherent full-mesh capabilities of MPLS networks.
What is a commonality between DMVPN and flex VPN technologies?
What is a commonality between DMVPN and FlexVPN technologies? FlexVPN and DMVPN use the new key management protocol, IKEv2. FlexVPN and DMVPN use IS-IS routing protocol to communicate with spokes. IOS routers run the same NHRP code for DMVPN and FlexVPN. FlexVPN and DMVPN use the same hashing algorithms.
Is DMVPN Cisco only?
This is a Cisco proprietary protocol. The Dynamic Multipoint Virtual Point Network feature allows you to easily scale your enterprise network. Even small companies use DMVPN with IPSec.
What is difference between Getvpn and Flexvpn?
What is a DMVPN router?
A dynamic multipoint virtual private network (DMVPN) is a secure network that exchanges data between sites/routers without passing traffic through an organization’s virtual private network (VPN) server or router, located at its headquarters.
What are the different types of DMVPN design?
There are three different types of DMVPN design: Provides hub-and-spoke tunnel deployment. This means GRE tunnels are only built between the hub and the spokes. Traffic destined to networks behind spokes is forced to first traverse the hub.
What is DMVPN and how does it work?
Introduction to DMVPN. 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 is the difference between DMVPN Phase I and Phase II?
The only advantage of the phase I setup is the fact the hub router’s configuration is much simpler. DMVPN Phase II: This phase involves everysite being configured with mGRE interface so you get your dynamic spoke-to-spoke connectivity, no more static tunnel destination’s will be configured.
What is the difference between DMVPN EIGRP and BGP?
This involve summarizing into the DMVPN cloud to provide (Remember EIGRP allows us to summarize out interfaces and BGP allows us to advertise aggregate addresses to neighbors). Along with configuring NHRP redirects and NHRP shortcut switching.
