Routing Using RIP version 2 en Cisco
In this article we continue with the presentation of a simple way to configure Routing in an environment of Cisco technologies RIP.
This time we had segmentaremos networks in previous examples subnets.
The aim is to analyze the behavior of the command network, to better understand the protocol settings.
(To calculate subnets, si no se os da bien, I suggest using this calculator)
In this case we chose the network 192.168.10.0/24 and segmented into subnets 30 hardware (/27). They could have chosen otherwise for segmentation, for simplicity all networks are equally segmented.
The system is as in figure:
Perform configuration, in the router R2:
R2>enable R2#configure terminal R2(config)#router rip R2(config-router)#version 2 R2(config-router)#network 188.8.131.52 R2(config-router)#network 184.108.40.206 R2(config-router)#network 192.168.10.0 R2(config-router)#no auto-summary
The command no auto-summary RIP prevents make an automatic network summary 192.168.10.0/24, if we do not, routers will not be able to know the subnets that mains. Thus we force them to publish as subnets are.
In all three routers, the command for subnets is the same: network 192.168.10.0
RIP can not specify the subnet mask, thus always all the main network subnets are published, and provided all the interfaces with addresses that are activated in mains.
In this case we can see how in R1, with that single command, activate the f0 / 0 interfaces (it is on the network 192.168.10.0/27) and f0 / 1 (it is on the network 192.168.10.96/27)
Although we tried to put the command network 192.168.10.96, RIP only recognize the main network, we can check by looking in the configuration file, the running-config:
namely, that with network you can not avoid announcing RIP subnets not want to announce, or activate some other and other non-interfaces. This not only happens in the RIP Cisco, It is generic in this protocol.
