Huawei equipment OSPF configuration is open to both PC1 and PC2, and layer 2 switches can only ping their own gateways. What's missing?

1. Only configured on layer 2 switchesDoes the PC need to write a gateway in ospf configurationThe IP address is not set, but the gateway address is not set, so you can only ping your own gateway. To solve this problem, you need to add a default route on the layer 2 switch, and the next hop should point to the gateway address. After this configuration, the layer 2 switch can ping other network devices. The specific configuration step is to enter "ip route 0.0.0.0 0.0.0" in the configuration mode of the switch, and it will be replaced with the actual gateway address.

2. Experimental purposes and resultsDoes the PC need to write a gateway in ospf configuration: The purpose of the experiment is to verify whether PC1 and PC2 can ping under a given network topology and IP/gateway settings. In a standard layer 2 switch environment, without additional routing configuration, this experiment usually fails because PC1 cannot find a routing path to PC2.

3. For example, when PC1 pines PC2, PC1 will check whether PC2's IP and itself are on the same network segment. If so, an arp request is directly issued to obtain the mac address of pc2. If you are not on the same network segment, you need to obtain the gateway's mac, hand over the ping packet to the gateway, and let the gateway help you send it. The role of the gateway is to whenDoes the PC need to write a gateway in ospf configurationWhen I don't know who to send the data to, I send it to the gateway.

4. The steps for configuring Layer 2 port isolation on Huawei switches are as follows: Create VLANs: First, create the required VLANs on the switch.

5. Configure PC2: IP: 19162Submask: 2525250 Gageway: 19161. Test connectivity PC1 Ping PC2, Ping 19162.

Huawei switch configuration enables cross-device intra-VLAN communication through VLANIF

Interworking between different VLANs of two cores of Huawei switches can be achieved by configuring the VLANIF interface. As a three-layer logical interface, the VLANIF interface can realize three-layer interoperability between different VLANs and different network segments. Its principle and specific operating steps are as follows: Principle The VLANIF interface is essentially a three-layer logical interface, and each VLAN corresponds to one VLANIF interface. When an IP address is configured for a VLANIF interface, the interface serves as the default gateway for users within the corresponding VLAN.

VLANIF realizes layer-three interworking between different VLANs by configuring the IP address of the logical layer-three interface and combining the routing and forwarding mechanism. Its core principle is to use the routing function of the layer-three switch to complete cross-VLAN packet forwarding. Basic characteristics of the VLANIF interface The VLANIF interface is a logical interface on a layer-3 switch, and is essentially a virtual layer-3 gateway.

Device connection: Devices on the same network segment are connected to the corresponding VLAN port, and all devices communicate through the IP address of the VLANIF interface. Advantages: Simple configuration, devices can be plugged in at will, without strict distinction between ports; Disadvantages: All devices are in the same broadcast domain (if VLANs are not subdivided), it is recommended that the number of devices should not exceed 200, otherwise a broadcast storm may be triggered.

Cross-VLAN forwarding is implemented through routers. Layer-3 static routing linkage solution If both switches are Layer-3 switches, you can create VLANIF interfaces corresponding to VLANs on the two devices and configure IP, then configure the network segment and opposite VLANIF interface address where static routes point to the other VLAN. The interconnection port maintains Trunk mode to release all VLANs, and you can directly realize ping across VLANs and devices.

The core step of configuring inter-VLAN inter-interoperability for a three-layer switch is to realize routing communication between different VLANs through the VLANIF interface. The specific configuration process is as follows: Prepare clear requirements before configuration: Users in different VLANs (such as User1 on VLAN10 and User2 on VLAN20) need to interwork across network segments, and the services are the same. Topology confirmation: Ensure that the layer-3 switch is connected to the user terminal and the physical link is normal (refer to the networking diagram).

The core of VLANIF's inter-VLAN communication is to open up layer-3 forwarding paths for different VLANs through layer-3 interfaces, so that originally layer-2 isolated VLANs can access each other. Basic principle: VLANs isolate broadcast domains in Layer 2 networks, and devices from different VLANs cannot communicate directly through Layer 2. VLANIF is a three-layer logical interface. After binding to a specified VLAN, it becomes the default gateway for devices within that VLAN.

How do PCs on two network segments ping each other through two routers

1. Environment construction Use two routers to simulate the network environments of the two companies respectively, ensuring that the router interfaces are clearly labeled to distinguish connections.

2. Another method is to insert a router between two network segments, which can be a normal router or a professional router. In this example, suppose we use a normal router. Connect PC1 to any LAN port of the router, and connect PC2 to the WAN port of the router.

3. For example, if network segment A equipment needs to access network segment B through gateway 19161, a route to network segment B needs to be configured on the gateway equipment. Typical scenario configuration example A single router connects two network segments to the network structure: the router connects network segments A and B respectively through two LAN ports (or one LAN port + one WAN port configured in LAN mode).

4. How computers whose IP is not on the same network segment ping each other for 15 minutes depends on what the situation is. If they are in the same internal network environment, it is a large local area network. For example, 19160.1/24 and 19161/24, they are not on the same network segment so they cannot ping directly.

ospf configuration commands

1. Enable the OSPF process and execute the command `router ospf `. The process number is a local significant number and does not need to be unified with other devices. Configure the router ID and execute the command `router-id `. It is recommended to use the device loopback IP to ensure that the entire network is unique.

2. The ospf configuration command is as follows: (1) bootproto=static.（2）onboot=yes。(3) Add a few lines at the end, IP address, subnet mask, gateway, dns server. OSPF is a link-state protocol.

3. Key commands for Huawei equipment OSPF configuration include: start the OSPF process and set routerid: [Huawei] ospf1: Start the OSPF process and enter the OSPF view. [Huaweiospf1]routerid 1: Set routerid to uniquely identify a router in an OSPF network. Create and enter the OSPF area view, and configure the network segments included in the area: [Huawei ospf1]area 0: Create and enter the OSPF area view.

4. Key commands for Huawei equipment OSPF configuration include: start the OSPF process and set routerid: [Huawei] ospf1: Start the OSPF process and enter the OSPF view. [Huaweiospf1]routerid 1: Set routerid to uniquely identify a router in an OSPF network.

Ensp, three routers and two PCs are connected. How can the two computers ping each other?

To realize the connection between the PC and the router in ensp, you can follow the following steps: Prepare to ensure that the ensp emulator is installed and starts normally.

Build a topology and add devices: Open the eSSP software, create a new topology, and drag two PCs (such as PC1 and PC2) from the device list. Connecting equipment: Direct connection: Use a Copper cable (automatic crossover cable) to directly connect the Ethernet interfaces of two PCs. Connect via switch/Hub: Add a switch or Hub, and use Copper cables to connect PCPC2 to the idle ports of the switch.

The two PCs are configured with corresponding interconnection interfaces as gateways, and the two routers can communicate with each other directly by writing static routes or running the OSPF protocol. OSPF routing protocol is a link-state routing protocol for Internet Protocol (IP) networks. The protocol uses the Interior Gateway Protocol (IGP) of a link-state routing algorithm to work within a single autonomous system (AS).

The ping command is based on the ICMP protocol. If a network device (such as a router) prohibits ICMP forwarding, the test will fail.

Ensp uses two switches and two PCs to ping according to the following steps: Open the ensp software, click New Topology at the top left of the software, and open a blank window. Click on the cloud icon in the device bar, select cloud, and drag it to the window. Right-click on the cloud device and select properties, select a udp binding in the binding information on the properties page, and click Add.
