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.
In this post I'm going to look at the characteristics of OSPF and EIGRP when used in a Dynamic Multipoint VPN (DMVPN). I will do my best not to play favorites and instead stick to the facts (yes, I do have a preference :-). To that end I will back everything up with data from my lab. The focus areas of the comparison will be: Scalability of the hub router's control plane Overall control plane 3) Also OSPF over IPSEC VPN between two sites, they can discover neighbour dynamically. There is not need to specify the neighbours manually. Yes, OSPF will autmotically discover the neighbours. No need to specify neighbours. Hope this helps.

When someone/people sign on the the vpn only one route will appear in the routing table of router in the ospf domain: O E2 192.168.254.128/25 [110/1] via 1.1.1.1 , 00:19:26, GigabitEthernet0/0 OSPF with IPsec VPN for network redundancy. This is a sample configuration of using OSPF with IPsec VPN to set up network redundancy. Route selection is based on OSPF cost calculation. You can configure ECMP or primary/secondary routes by adjusting OSPF path cost. Because the GUI can only complete part of the configuration, we recommend using
This article illustrates how to configure a Dynamic Route-based VPN using OSPF. 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 configuration on PPP interfaces often is a subject to misunderstanding. You need to keep in mind two things: There is no need to explicitly configure an interface in "/routing ospf interface" to start running OSPF on it. Only "routing ospf network" configuration determines whether the interface will be active or not. OSPF works VPN Works, but only if configured manually. 3 Issues: CA Cert can't be saved through UI. Simply disappears when saving or applying. Network can't be saved through UI. Simply disappears when saving or applying. TLS ta.key has wrong permissions. OSPF can cross VPNs without extra setup. But only over VPN Tunnel Interfaces. (note there is a bug with this on the latest version) You shouldn't have any issues on a straight MPLS connection unless you are adding additional encryption to the connection. Having only have a single path to each site doesn't make sense for OSPF.
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 illustrates how to configure a Dynamic Route-based VPN using OSPF. 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. 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-interface MD5 Authentication: (Defaults to disabled) If this is enabled, MD5 hashing will be used to authenticate potential OSPF Authentication Key: The MD5 key number and passphrase. Both of these values must match between any devices that you wish Jan 14, 2019 · In the extended application of OSPF VPN, the MPLS VPN backbone network serves as Area 0. OSPF requires that Area 0 be contiguous. Therefore, Area 0 of all VPN sites must be connected to the MPLS VPN backbone network. If a VPN site has OSPF Area 0, the PEs that CEs access must be connected to the backbone area of this VPN site through Area 0.
