1, about TE Flow engineering background Knowledge Introduction:
Why is there a te flow of engineering production?In the real production network, IGP often some fatal restrictions, such as OSPF is based on cost to select the path, the cost of the smaller the more priority. But sometimes the smaller the cost, does not mean that the link load is small. For example, there is a link is 100M, with 99M,

After configuration, you can use "show ip route" in privileged mode to view the route table of the router !!
3. Configure MPLSPE and P routers)R2: PE1 (config) # ip cef // enable the fast forwarding function PE1 (config) # int f0/1PE1 (config-if) # mpls ip // enable
. 20 bits are 16-1048575, and the default value is 16-10 0000 for IOS. IGP is enough, but BGP may not be enough. You can view and modify the label range.

In addition to improving the speed of protection and recovery, the advantage of fast rerunning can avoid repeated protection in reliable networks and unnecessary consumption of core network resources by configuring protection capabilities in poor network links. MPLS fast re-routing technology provides protection switching within 50 ms and can be used as an alternative to SDHAPS pro
What is the premise of using MPLS traffic engineering for CISCO? or MPLS te configuration logic:
Cisco IOS software version that supports MPLS traffic engineering.
The network needs to start CEF.
The link state protocol used as IGP OSPF or Is-is. Only these two protocols can support TE. (OSPF provides a class tenth
R0 creates a tunnel to R1 to enable multicast. It's very simple to scale up and you can see the configuration at first glance. Wvrp has passed.

4.2 related configuration of access switches# # In this example, we are connecting to an access switch where the GI0/1 port is allied to the core switch. It also means that we need to configure GI0/1 as trunk port. The specific configuration is as follows:D-2960-3 (config) #int GI0/1D-2960-3 (config-if) #swD-2960-3 (config-if) #switchport moD-2960-3 (config-if) #

The database.php usage of codeigniter configuration is analyzed in this paper. Share to everyone for your reference, specific as follows:
The CodeIgniter database configuration file is located in application/config/database.php, which defines a two-dimensional array of $db, with reference to the following file:

$db [' Default '] [' hostname '] =
The routes.php usage of codeigniter configuration is analyzed in this paper. Share to everyone for your reference, specific as follows:
An array named $route is defined in application/config/routes.php to set the default route and 404 pages and to set up some matching methods.
The default configuration is as follows:
$route [' default_controller '] = "welcome";
$route [' 404_override '] = ';
