IGRP protocol for CISCO router configuration

IGRPIs a dynamic distance vector routing protocol designed by Cisco In The Middle Of 1980s. Use a combination of user configuration scales, including latency, bandwidth, reliability, and load.

By default, IGRP sends a route update broadcast every 90 seconds, namely, 270 seconds in three update cycles), and no update is received from the first vro in the route, the route is declared inaccessible. After 7 update cycles, namely 630 seconds, the Cisco IOS software clears the route from the route table.

1. Related commands

Task commands

Specify the router igrp autonomous-system1 using the RIP Protocol

Network connected to the vro

Specify the Node address neighbor ip-address adjacent to the vro

Note: 1. autonomous-system can be created at will, not in the actual sense of autonomous-system, but the autonomous-system must be the same for Routers running IGRP to exchange route update information.

2. Example

 

 

The configuration code is as follows:

 
 

  
  
Router1：  
  
  
 
  
  
router igrp 200  
  
  
 
  
  
network 192.200.10.0  
  
  
 
  
  
network 192.20.10.0

There are still many IGRP knowledge points. I hope you will pay more attention to them and we will present them to you in future articles.
