What is stub command?

What is stub command?

The EIGRP stub command is used with the connected and static keywords to configure the device as a stub that advertises connected and static routes.

What is DMVPN used for?

Dynamic Multipoint Virtual Private Network (DMVPN) is a solution which enables the data to transfer from one site to another, without having the verification process of traffic. That use to be held at main VPN server of the concerned organization.

Is DMVPN hub and spoke?

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 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. VPNs connect each remote site to the company headquarters.

What is a stub routing?

Stub routing is an EIGRP feature primarily designed to conserve local router resources, such as memory and CPU, and improve network stability. The stub routing feature is most commonly used in hub-and-spoke networks. This feature is configured only on the spoke routers.

What is a stub network answer?

A stub network, or pocket network, is a somewhat casual term describing a computer network, or part of an internetwork, with no knowledge of other networks, that will typically send much or all of its non-local traffic out via a single path, with the network aware only of a default route to non-local destinations.

Is DMVPN encrypted?

Encryption. As with GRE tunnels, DMVPN allows for several encryption schemes (including none) for the encryption of data traversing the tunnels. For security reasons Cisco recommend that customers use AES.

How old is DMVPN?

DMVPN was introduced by Cisco 15 years ago around 2002. Biggest driver for the technology was hybrid WAN, which provided the customers the ability to use commodity Internet to augment their existing MPLS connectivity.

Is DMVPN Cisco proprietary?

DMVPN is a dynamic VPN technology originally developed by Cisco. While their implementation was somewhat proprietary, the underlying technologies are actually standards based.

Is DMVPN SD WAN?

While IPsec VPN tunnels are hardcoded and essentially “nailed up” between two locations, DMVPN builds tunnels between locations as needed. It does this using typical routers with no additional feature capability, as is the case with SD-WAN. DMVPN tunnels are designed as a mesh network, as opposed to hub and spoke.

What are the three phases of DMVPN?

In its simplest form, DMVPN is a point-to-multipoint Layer 3 overlay VPN enabling logical hub and spoke topology supporting direct spoke-to-spoke communications depending on DMVPN design ( Phase 1, Phase 2 and Phase 3 ) selection.

What is stub?

A stub autonomous system that is connected to only one other autonomous system, through which it gains access to the Internet. This is also called a stub AS, which characterize the great majority of AS connected to the Internet.
