Function execution environmentSimple code:Copy codeThe Code is as follows:Function say (msg, other ){Var str = "nobody say :";This. name = 'dummies ';Function method () {}; // var method = function (){};Alert (str + msg );}Say ('Hello World ');Alert (name); // dummies motto When you call the say method, the first step is to create its execution environment. During the creation of the execution environment,

Description: After the use of IP to identify each network node, if the two nodes separated by multiple network nodes to communicate, need to "man-in-the-middle" strings, the step by step notice a node data, to go to the end of the node step-by-step how to go.Static routing: Manually configure static routing information that can be forwarded using a leased line interface or a next-hop IP address based on the routing information when forwarding packets with matching destination addresses.Advantage

Above we have realized that RIP (routing Information Protocol) EIGRP (Enhanced Gateway Routing protocol), we come to know the following routing protocol OSPF (Open Shortest Path precedence protocol) also called it as an interface-sensitive routing protocol.OSPF Link State Protocol(Open short Path first) Open Shortest route priority protocolLet's take a look at the OSPF protocol at 1.1 o ' walk slowly. 1, the OSPF routing protocol is a typical link sta

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 detail, and then see where the difference, and finally there is a OE2 routing problem is for

I. DMVPN Tan Yun Double Center A. By modifying the OSPF cost value of the two-center tunnel interface, only the routers behind the center will be routed to spoke B. By modifying the OSPF cost values for the physical interface behind the two centers, you can influence spoke select different hubs to the network behind the center C. Because there is only one virtual tunnel, it is not possible to implement a different hub by adjusting the OSPF cost of the spoke tunnel interface to the network beh
