in the reading OpenStack each component source code process, discovers all modules like Nova,neutron and so on, all through the WSGI way provides the restful API externally.
and in the process of using WSGI, it involves paste,routes,webob the use of these Python third party libraries. So if you want to understand OpenStack's code to provide restful APIs, you have to learn Python WSGI first and understand the role paste,
External routes that are redistributed from the OSPF ASBR will generate two types of routes for OE1 and OE2 to be delivered in the OSPF area.
The type of Cisco default external route is OE2. The default metric=20 is not cumulative based on the cost of the link.
The OE1 must be manually specified before it can be passed within the OSPF area. In this document will be OE1 and OE2 through the experiment in de

At 5.4, the route is still

When I was 5.6, I moved it out of the app directory.

For an MVC framework, how to parse the route is a very important issue, so it is really good to change.
It is also learned that the Laravel route is based on Symfony, the slower part of Laravel should be routed, Laravel based Lumen for performance, abandon Symfony routing components to use Fastroute, good news is:
In the actual development, nested routines from often used, the basic usage is very simple, today is not to say how to use the nested routines, but in the process of using the two points found in the processing of small details. nested routines are selected by default in the first Zi Lu by the
In one such interface, the bottom of the five tab should obviously be five routes, and now on the home page this route has three tab, then the Three tab should
interface, based on the calculation criterion of the RPF interface, the interface that receives the message is cut from the list of outgoing interface, RPF interface is calculated by RP, and a S, G) entry is generated. This ensures that the router that fails to reach the threshold can still receive messages correctly from the shared tree.
3. A very important principle is that when the routing table contains *, G) and S, G), data will be forwarded based on S, G. At the same time, this process tr
AngularJS is used to perform security processing on routes.
Introduction
AngularJS has been used for a long time since its appearance. It is a javascript framework used to develop SPA applications. It has some good features, such as bidirectional binding and instructions. This article mainly introduces Angular routing security policies. It is a Client Security Framework developed and implemented by Angular. I have tested it. In addition to ensuring cl

More mobile phone development technology, interested friends can discuss with me. Development tools:The choice of development tools is mainly to see everyone's habits, I personally prefer to use ECLISPE, the function is very strong, but also very good to expand other functions. When you have a beginner you

Using the following five types of data packets:

Many wireless products now have universal functions. What is universal function? That is, product A can be used as product B, that is, A wireless product can implement the functions of other products through other modulation. This article describes how to use a wireless route as a wireless switch.
To put it simply, use a wireless route as a wireless switch and set only three points:
① Network parameter → LAN port setting: Change the ip address to another network segment, and the IP address can
Take care of these pitfalls when buying wireless routes: Gigabit network ports and 5 ghz are the most critical, Gigabit 5 ghz
315 is coming soon. Various consumer rights protection events have become the main character, and counterfeiting is a theme that has never changed for 315. Today, let's talk about text games printed by wireless router manufacturers on packaging. When selecting a wireless router, we often see "Gigabit", "dual-band", "wall-cross
What is the difference between new, collection, and member in Rails Routes? railsroutes
By default, there are seven RESTful routing verbs (index, show, create, new, edit, update, and destroy ). Sometimes we need to customize the route, then we need to use the: on parameter. : The on parameter has three values: collection, member, and new.
If you want to add a member route, you can:

Q: There are three CIDR blocks, each of which contains two computers. The IP address segment in CIDR Block A is 10.0.0.2 ~ 10.0.0.2. The IP address segment in CIDR Block B is 192.168.0.2 ~ 192.168.0.3, the IP address segment in CIDR Block C is 172.160.2 ~ 172.160.3. Now we need to connect the three CIDR blocks to form a LAN. What should I do?
A: In small and medium-sized LAN networks, you can use two routers to connect the three CIDR blocks. You only need to tell "router A" the address of "CIDR
Static Routing can be divided into the following three parts:
1. The network administrator configures static routes.
2. Add the configured static route to the routing table.
3. the router uses this static route to forward data packets.
Configuration instance:
In the figure, all devices forward data packets to the internet through the vro whose host name is it168. Vro168 it168 uses a serial line to connect to the DNS server provided by the ISP. T
The emergence of wireless networks has a huge impact on traditional network technologies. How should we set up wireless routes? The following articles will help you answer your questions.
Previously has been to others installed are wired router, recently had the honor to install a TP-LINK wireless router, learned a few strokes, a small sense of Special Records.
1. Modify the Login Password
Connect to the route. First, log on to the route and change th
the Internet should not be part of your internal network. Therefore, IP addresses such as 192.168.X.X, 172.16.X.X, and 10. X must be blocked.
Finally, communication with the source address or all the communication with the destination address that cannot be routed should be allowed through this router. This includes the return address 127.0.0.1 or class E address segment 240.0.0.0-254.255.255.255.
8. Maintain the physical security of the router
From the perspective of network sniffing, routers
the foundation has been, there is no too much problem. In the premise of not having the basis of the direct learning Ajax, like "floating sand on top of the building", so, the Ajax learning order is arranged here.Nineth Step Learning Ria TechnologyRia:rich Internet application can be regarded as an attempt to combine the advantages of C/s and b/s. In terms of specific technology, the main point is Microsoft's Silverlight (WPF_E), after all, the road ahead is the Microsoft line. But the current
reach the target. If there are two vrouters with different speeds or bandwidths to the same destination, but the hop count is the same, RIP considers the two routes to be of the same distance. The maximum number of hops supported by RIP is 15, that is, the maximum number of routers to be routed between the source and destination networks is 15, and the number of hops is 16, which indicates that the network cannot be reached.

4. Even if there are redundant lines, the SLA still cannot achieve the expected effect. Redundant lines are usually the default routes.
If the target of the SLA is an address that can be reached by a redundant line, the track will be continuously down-> up-> down. The reason is understandable. See figure 1;
If the target of the SLA is reachable, the track will never be restored. The reason is as follows
