I. Overview:
Cisco routers have a lot of IKEV2 for the IKEV2, so you can configure them with little configuration.
Two. Basic ideas:
A. Configure flex VPN on both sides in a svti manner
B. No dynamic routing, configuration of static routes, if one side with Dvti, you need to configure static routes on both sides
Three. Test topology:

Two. Basic ideas:
A. Before configuring certificate authentication, you need to configure clock synchronization
B. Certificate authentication, identity can be set to FQDN, but the
In the third and fourth messages of IKEv2, both parties will send an auth payload to each other to prove their identity. This process is implemented by signing the first message sent by each other. For example, if a responder wants to prove its identity, it needs to cache the entire message when it sends an ike_sa_init message. Then, before sending ike_sa_auth, connect the cached ike_sa_init message with nonce_ I and the MAC value of its own ID, and u

I. Software Description
IPsec is a type of Virtual Private Network (VPN) used to establish an encrypted tunnel between the server and the client and transmit sensitive data. It consists of two phases: the first phase (Phrase 1, ph1), the exchange key to establish a connection, the use of Internet Key Exchange (ike) protocol; the second phase (Phrase 2, ph2 ),

You only need to configure the two peer terminals. Because the Intranet Communication of vpn can be completely dependent on the routing implementation.Someone asked, Where are the negotiated parameters? In fact, if you do not specify it, it is

Solution 2: wired
The cable solution can only deploy single-mode optical fiber cables at a distance of 12 kilometers, which is more time-consuming and costly. You can say you don't have to think about it.
Solution 3: Internet + VPN
The Internet can be said to be a public wide area network, and many telecom operators have established a four-way and eight-way long-distance network, which makes it possible for our compan
default when wp8.1 connects to the IKEv2 vpn, the user name or password is displayed during the connection. There are two solutions:
Method 1: Set/usr/local/etc/ipsec above. the last line of the secrets file is changed to % any: EAP "[Password]", so that you can use any user name to log on without any errors.
Method 2: Use FreeRADIUS to filter out the domain of the login name. Refer to connection: Remove F

In addition, VPN Reconnect can also maintain connections when mobile users or devices moving between access ports change their geographic locations frequently.

Rd (route-distinguisher) is used to identify different VPN instances on the PE device. Its main function is to achieve address multiplexing between VPN instances. It and the IP address constitute a 12byte vpnv4 address space, rd and the route are carried together in the bgp update message and published to the peer end. On the one hand, we
I have been studying CCNP Security Firewall v1.0 recently. Now the research is complete! It is found that Cisco ASA 8.4 has changed a lot. It is more and more like the checkpoint firewall. The global access control list, whether it is NAT or recently, is exactly the same as that of the cp firewall. After the Firewall v1.0 study is completed, the next research goal is VPN v1.0, which mainly introduces VPN on
