February 14th, 2020 in ENCOR Knowledge Go to comments. Configuring DMVPN. DMVPN can be configured in three different methods, each method is often called a “phase”: 1) DMVPN Phase I (Spoke-to-Hub only): + mGRE is configured on Hub, p2p GRE is configured on Spokes Cisco DMVPN Configuration Example - Networks Training In this Cisco DMVPN configuration example we present a Hub and Spoke topology with a central HUB router that acts as a DMVPN server and 2 spoke routers that act as DMVPN clients. All the routers involved in this tutorial are CISCO1921/K9

Tip: At the time of this writing the recommended Alpine version for building a DMVPN should be at minimum 2.4.11.Don't use 2.5.x, or 2.6.0 since the kernel has in-tunnel IP fragmentation issues. Alpine 3.0 has also a Musl issue in getprotobyname(). Alpine 2.7.x has been thoroughly tested and 3.0.3 hasn't shown any issue so far. Configuring Cisco Dynamic Multipoint VPN (DMVPN) - Hub Our DMVPN Introduction article covered the DMVPN concept and deployment designs. We explained how DMVPN combines a number of technologies that give it its flexibility, low administrative overhead and ease of configuration. This article will cover the configuration of a Cisco DMVPN including Hub, Spokes, Routing and Protecting the mGRE Tunnel. GNS3 Lab—Introduction to DMVPN - Intense School
