In my lab, I wanted to utilize a dynamic routing protocol for my hub and spoke VPN topology. I decided to first try it with OSPF (BGP configuration here).The requirements were to utilize only one tunnel interface on the hub device for all IPSec tunnels, as well as deny all traffic between spoke sites.
KB ID 0001151 Dtd 03/02/16. Problem. This article is a supplement to the earlier one on Setting Up DMVPN.It covers how to use OSPF over the top of DMVPN. This is the topology I’m going to use; This lesson explains how to use OSPF as the PE-CE routing protocol for MPLS L3 VPN. The configuration is very similar to PE-CE RIP or PE-CE EIGRP but OSPF has some extra options as a link-state routing protocol. Apr 22, 2013 · -Select each ovpn connection and set the metric to 10 for the primary route and set the metric to 20 for the secondary vpn. Create a description to help identify the correct vpn when looking at all the interfaces. You will have 2 OSPF interfaces for each remote site, one for the normal primary path and one for the secondary backup path. Network (VPN) implemented with MPLS VPN technology. Objectives Upon completion of this module, the learner will be able to perform the following tasks: Describe the OSPF operation inside a VPN Describe enhanced OSPF hierarchical model Describe the interactions between OSPF and MP-BGP Use OSPF as the PE-CE routing protocol in complex MPLS VPN 2) If we run dynamic routing protocol over IPSEC VPN tunnel then no need for static NHTB. It would be automatically popolulated. Yes it is correct , you do not need static NHTB . 3) Also OSPF over IPSEC VPN between two sites, they can discover neighbour dynamically. There is not need to specify the neighbours manually. Create separate OSPF templates for the two OSPF routing types. Create a VPN feature template to configure VPN parameters for either service-side OSPF routing (in any VPN other than VPN 0 or VPN 512) or transport-side OSPF routing (in VPN 0). See the VPN help topic.

OSPF Over VPN Be easy on me, I'm new to ospf, finally figured out how to keep the tunnel up when activating ospf my question. i have 3 routers all connected to each other so that there are 2 paths to all subnets between the routers. By doing this, the VPN sub-interface provides a vague equivallence to having a tunnel interface, which allows dynamic routing protocols (with some tweaks) to run over the VPN. This article will show how to configure this VPN, and get OSPF running across it.
