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.. The first part is about configuring LDP, VRFs and iBGP between the PE routers. 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 IPSec VPN Tunnel Hello. I'm having a trouble setting up OSPF over IPSec in the network of my company. We actually have created VPN tunnels between each branch office. This tunnels are in a simple configuration with static routes working well. We want to configure OSPF over this tunnels for, in a future, establish a dynamic full mesh The BGP/MPLS VPN backbone acts as either an OSPF backbone (area 0) or an OSPF area above the backbone. In this topology, OSPF is the routing protocol between the CE router and the PE router. This OSPF link can be configured in area 0 or any other OSPF area.

In Dynamic Route Based VPN, network topology configuration is removed from the VPN policy configuration. The VPN policy configuration creates a Tunnel Interface between two end points. Dynamic routes can then be added to the Tunnel Interface.
OSPF Hello messages are sent over multicast by default. However, IPSec does not support multicast over a VPN tunnel. Consequently, OSPF adjacency using multicast cannot be established over IPSec VPN tunnels. Cisco ASA provides a solution to this problem by supporting the configuration of statically defined neighbors with the neighbor command.

In this example, each site uses OSPF for dynamic routing of traffic. The tunnel IP address on each VPN peer is statically assigned and serves as the next hop for routing traffic between the two sites. Configure the Layer 3 interfaces on each firewall. Select . OSPF over VPN is required if we are running OSPF inside our network and we need to extend the OSPF network to the other end of the site as well. By configuring the OSPF over VPN dynamically the sites can be added to route the VPN traffic. Configuration. To configure OSPF on the MX, navigate to Security & SD-WAN > Configure > Site-to-site VPN > OSPF settings.. Enabling Advertise Remote routes will provide additional configuration options: . Router ID: The OSPF Router ID that the MX will use to identify itself to neighbors. Area ID: The OSPF Area ID that the MX will use when sending route advertisements. This article describes how to configure OSPF over dynamic IPSEC VPN. The setup includes single spokes with hub location which would be assigning IP addresses to the spokes via dial-up VPN. A dynamic IPsec tunnel will be established which will allow OSPF through it. Solution. Hub Configuration. 1) Configure VPN phase-1. # config vpn ipsec phase1 OSPF Hello messages are sent over multicast by default. However, IPSec does not support multicast over a VPN tunnel. Consequently, OSPF adjacency using multicast cannot be established over IPSec VPN tunnels. Cisco ASA provides a solution to this problem by supporting the configuration of statically defined neighbors with the neighbor command. A typical use case for this is when router is sourcing OSPF packets and traffic selectors for IPsec allows OSPF packets (protocol number 89, group 224.0.0.5 & 224.0.0.6). As of release 12.4(9)T those packets will be put into the tunnel and encrypted.
