protocol between as is called the External Gateway Protocol External Gateway Protocol (also called Inter-Domain routing protocol): there are two types of inter-domain routing protocols: externalGateway Protocol (EGP) and Border Gateway Protocol (BGP)2) Dynamic routing according to the algorithm can be divided into: Distance vector
Note: PBR was previously a major tool used by Cisco to discard messages. For example, set interface null 0, which, according to Cisco, would save a bit more overhead than the ACL's deny. Here I remind: Interface NULL 0No IP unreachable//Join this commandThis avoids the return of many ICMP unreachable messages because of the large number of packets discarded. When a three-tier device forwards a packet base

Routers are packet forwarding devices that work in the third layer of the OSI Reference Model-the network layer. Routers implement network interconnection by forwarding packets. Although routers can support a variety of protocols (such as TCP/IP, ipx/spx, AppleTalk, etc.), most routers in China run TCP/IP protocol. Routers typically connect two or more logical ports identified by an IP subnet or Point-to-Point protocol, with at least one physical port. The router determines the output port and t
efficiency of the router configuration, in the Cisco Device command can be abbreviated "typing the first few letters of the command, when the first few letters of the command press the tab can be filled, or directly enter can also execute the command". ）Note: Write is the Save command, and this command executes in privileged mode. In other modes (not available in user mode), you can add do enforcement before the command.3, after the completion of th
1. Start the OSPF protocol To start the OSPF routing protocol on a CISCO router, two steps are generally required:1) Start the OSPF protocol process:Router (config) # router ospf 2) define the network of the vro:Router (config-router) # network The OSPF protocol is started through the Router ospf command. The OSPF protocol Process id is only a value related to the current vro and has no relationship with o
Cisco single-ARM routing configuration One-arm routing, which is to set up multiple logical subinterfaces on the router, one VLAN for each sub-interface. The data on each sub-interface is passed on the physical link to be labeled encapsulated. Cisco devices support ISL and 802.1q (dot1q) protocols. Huawei only support
Problem description You can define your own rules to route data packets, not just the destination address. Here You can learn how to use policy-based routing to solve this problem. In specific applications, policy-based routes include: ☆Source IP address-Based Policy Routing ☆Policy Routing Based on data packet size ☆Application-Based Policy

While dynamic routing protocols provide easy deployment, there will be situations in which more specific selection of routing paths can be advantageous. cisco Policy Based Routing provides a flexible mechanic for network administrators to customize the operation of the routing
The concept, installation, configuration, and use of GNS3 are described earlier, and this article describes how to use the GNS3 configuration IOU to enable routing Exchange experiments using GNS3 and Cisco IOU.Since this is a long story, I'll go through the outline first:1. Introduction to IOU Simulation environment2. Preparation of IOU Software environment3. Installation, import, and configuration of VMwar
