Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Introduction

The Dynamic Multipoint VPN (DMVPN) feature allows users to better scale large and small IPSec VPNs by combining generic routing encapsulation (GRE) tunnels, IPSec encryption, and Next Hop Resolution Protocol (NHRP) to provide users with easy configuration through crypto profiles, which override the requirement for defining static crypto maps, and dynamic discovery of tunnel endpoints.

Prerequisites

Requirements

There are no specific requirements for this document.

Components Used

The information in this document is based on the software and hardware versions below.

  • Cisco 2691 and 3725 routers

  • Cisco IOS® Software Release 12.3(3)

Note: Multiple IPSec pass-through is only supported on Cisco IOS Software releases 12.2.(2)XK and 12.2.(13)T and later.

Output from the show version command on the router is shown below:

Background Theory

The feature works according to the following rules.

  • Each spoke has a permanent IPSec tunnel to the hub, not to the other spokes within the network. Each spoke registers as clients of the NHRP server.

  • When a spoke needs to send a packet to a destination (private) subnet on another spoke, it queries the NHRP server for the real (outside) address of the destination (target) spoke.

  • After the originating spoke learns the peer address of the target spoke, it can initiate a dynamic IPSec tunnel to the target spoke.

  • The spoke-to-spoke tunnel is built over the multipoint GRE (mGRE) interface.

  • The spoke-to-spoke links are established on demand whenever there is traffic between the spokes. Thereafter, packets are able to bypass the hub and use the spoke-to-spoke tunnel.

The following definitions apply to the rule set.

  • NHRP—A client and server protocol where the hub is the server and the spokes are the clients. The hub maintains an NHRP database of the public interface addresses of the each spoke. Each spoke registers its real address when it boots and queries the NHRP database for real addresses of the destination spokes in order to build direct tunnels.

  • mGRE Tunnel Interface—Allows a single GRE interface to support multiple IPSec tunnels and simplifies the size and complexity of the configuration.

Note: After a preconfigured amount of inactivity on the spoke-to-spoke tunnels, the router will tear down those tunnels to save resources (IPSec security associations [SA]).

Note: The traffic profile should follow the 80-20 percent rule: 80 percent of the traffic consists of spoke-to-hub traffic, and 20 percent of the traffic consists of spoke-to-spoke traffic.

Verify

This section provides information you can use to confirm that your configuration is working properly.

Certain show commands are supported by the Output Interpreter Tool (registered customers only) , which allows you to view an analysis of show command output.

  • show crypto engine connection active—Displays the total encrypts and decrypts per SA.

  • show crypto ipsec sa—Displays the stats on the active tunnels.

  • show crypto isakmp sa—Displays the state for the the ISAKMP SA.

Troubleshoot

This section provides information you can use to troubleshoot your configuration.

DMVPN Tunnel Flaps Intermittently

Problem

DMVPN tunnel flaps intermittently.

Solution

When DMVPN tunnels flap, check the neighborship between the routers as issues with neighborship formation between routers may cause the DMVPN tunnel to flap. In order to resolve this problem, make sure the neighborship between the routers is always up.

Troubleshooting Commands

Note: Before issuing debug commands, please see Important Information on Debug Commands.

  • debug crypto ipsec—Displays IPSec events.

  • debug crypto isakmp—Displays messages about Internet Key Exchange (IKE) events.

  • debug crypto engine—Displays information from the crypto engine.

Additional information on troubleshooting IPSec can be found at IP Security Troubleshooting - Understanding and Using debug commands.
