# 1 teach and how to implement a dormitory between unicom, 1.2.3 dormitories have ping, 1.2 teach has ping, no. 1 dormitory building ping1 teach when display connection timeout

I just did the experiment under your already do, I don't know you specific configuration, I will talk about my thoughts - all my PC will be divided into different vlan, convergence and core switch by vlanif configuration IP address do three layers of communication, in theory can all pass, but there are two need to pay attention to:
1, the topology, all switches trunk interface must be allowed to release all the vlan;
2, gathering switches must be configured in the corresponding routing, the next-hop vlanif mouth the IP address of the corresponding to the core switch I (I bother to direct configuration of the default static routing),
The above two points I am in the process of configuration, the two problems of the above two points as long as there is a didn't do, will you describe network failure phenomenon,

Hello, first of all I have done, the second gathering switches must be configured in the corresponding route, the route there is no ah, I figure that I am also to give each a convergence layer switches connected a routing and configuration

CodePudding user response:

Without adding additional routers, switches on use is based on the three layers of the communication function of vlanif interface, layer 3 switches itself to have the routing function,
You in switches, for example, through the command interface vlanif 10 and interface vlanif 20 created vlanif10 and vlanif20 two interfaces, the two interfaces is quite so the physical interfaces on both sides of the router, and in these two interfaces configured with the IP address, your switches is equivalent to a router, switch on both sides can like routers communicate across different network segment vlan by three layers, finally check the path table each switch, if there is no need to route entries, configuration, this time switches have the function of routing,
I do not know I have a clear,,,

Core exchange, all VLAN

I always feel where you have any questions, try out or the request timeout

High-definition pictures I see you, you this is big problem, the network planning in my opinion the whole has a problem, don't know what is your plan or how,
First of all, you put the whole network is divided into vlan10 a vlan, although in terms of the short network configuration vlan10 lost its meaning, but just make sure all the IP address is exposed to the same network segment, also can pass, but you are the same vlan10 distribution under the different segments of the IP address, this time don't create another vlan how all don't, you can look at the pictures above, I the IP address of the two computers is different network segments, so I used a different vlan,
And adjacent switches the same vlanif mouth IP address must be the same network segment, you gather switch 1 configuration, 40.1 60.1 core switch configuration, convergence switch configuration, 50.1 2 adjacent section in different network IP address, and the IP address to the default gateway for your PC, gateway and the PC into different segments, this configuration is wrong,
The entire network you only have one teach and the second is the same network segment, so the two PCS can pass, but you said that the three dormitories also can pass, this I can't understand, don't know whether you are wrong, or is to configure the other things, in terms of the picture three dormitory building elements, and certainly not the myself also did experiments also impassability,
It is recommended that you check out others on the Internet made switches three-tier communication related experiments, to understand and then to do myself,
