Run Telnet settings in vrotelnet Management

Telnet can help us remotely manage some network devices. So here we are talking about how to run Telnet in vrotelnet management. In the network management process, you often need to modify the vro configurations, such as modifying the wide area network port and LAN port IP address of the vro. The vro configurations are usually not local, this makes modification troublesome. In practice, I encountered such a problem. However, after exploration, I can easily solve this problem.

Network Environment

The entire network consists of two parts: local network and remote network. The local area network and remote network of the local area network are equipped with a Huawei Quidway R2501 router, using the Server Load balancer technology, two 64-K digital channels provided by a single multi-access device are used to achieve K rate connection. The AUX port is used as a backup connection. Once the microwave number fails, the dial-up connection can be enabled to implement the backup function, the connection mode.

 
 

  
  
The local area network is 10.138.184.0, and the local area network port address of the local router is 10.138.184.21.
  
  
The remote LAN is 10.138.185.192, And the LAN port address of the remote router is 10.138.185.193.
 
 

Step-by-Step Modification

According to the unified planning of our Bureau, the remote LAN is switched to the 10.138.185.0 (subnet mask: Subnet Mask mask) CIDR block. To ensure normal communication between the two networks, you need to modify the lan ip address configured for the remote router and the route configured for the local router.

1. Log On As an administrator on the vro of the headquarters, add a route to the remote network, run Telnet 10.138.184.21, set the privileged mode to enable, and enter the password. Then, run the config command to enter the configuration mode. Add two static routes (serial0 and serial1 have the same priority for load balancing ):

 
 

  
  
ip route 10.138.185.0 255.255.255.224 10.139.184.246  
  
  
ip route 10.138.185.0 255.255.255.224 10.139.184.250 
 
 

2. log on to the remote router as an administrator and modify the LAN port IP address configured for the remote router. Run Telnet 10.138.185.193, set the privileged mode to enable, and enter the password. Enter the Ethernet port configuration mode:

 
 

  
  
Quidway (Config) # interface ethernet 0;
  
  
Set the IP address of the Ethernet port to 10.138.185.1;
  
  
Quidway (Config-if-Ethernet0) # ip address 10.138.185.1 too many connections.
 
 

3. log on to the vro configuration of the Headquarters as an administrator and delete the route from the headquarters to the original remote network (10.138.185.192. Delete the original three static routes and use the Write command to save the configuration.

Notes

If you ignore these two things, the operator will give up. First, after the configuration modification is complete, you must execute the write command. Otherwise, all the modifications made after the vro restarts will be lost. Second, in order to ensure that the remote network workstation can access the local network host, the default gateway of the remote LAN workstation should be modified to configure the LAN port address 10.138.185.1 for the modified remote router.
