Configuring Static Route

Lesson 1: Configure static routing

Lesson 2: Configuring Routing default (default route)

I. Concept

– Routing is the process that routers perform to transfer data packets to the destination network. The router is based on the destination IP address of the packet to packet to the interface in the right direction to the final destination. (Please see the article: The defensive on Router )

– For static routing, the path information from the network administrator is assigned to the router. Then the functional administrators to update, delete the information about the path to router.

II. Features:

– Apply for a small network environment (less than 5 router)

– Do not consume link bandwidth for messages between routers on the way

– Do not consume system resources Router path computation as dynamic routing

– Secure Router only works because based on the way that the designated Admin

– Very difficult to troubleshoot, to reconfigure when there are changes in the network address of the device as well as

III. Configuration

– First we configure IP on two routers

At Router0

Router> en

Router # conf t

Router (config) #hostname Router0

Router0 (config) #interface f0 / 0

Router0 (config-if) # ip address 10.0.0.1 255.255.255.0

Router0 (config-if) #no shutdown

Router0 (config-if) #exit

Router0 (config) #interface f0 / 1

Router0 (config-if) # ip address 192.168.1.1 255.255.255.0

Router0 (config-if) #no shutdown

At Router1

Router> en

Router # conf t

Router (config) #hostname Router1

Router0 (config) #interface f0 / 0

Router0 (config-if) # ip address 10.0.0.2 255.255.255.0

Router0 (config-if) #no shutdown

Router0 (config-if) #exit

Router0 (config) #interface f0 / 1

Router0 (config-if) # ip address 172.16.1.1 255.255.255.0

Router0 (config-if) #no shutdown

 

– To enable static routing we have two ways to configure the following:

Method 1:

Router (config) # ip route <Network_dich> <Subnet Mask of Network_dich> <IP nexthop>

Either way 2 :

Router (config) # ip route <Network_dich> <Subnet Mask of Network_dich> <exit Interface>

For example, do the following models:static5 Configuring Static Routing (Configuring Static Routing)

Figure 1: Diagram showing the configuration using Static

Option 1: Router (config) # ip route <Network_dich> <Subnet Mask of Network_dich> <IP nexthop>

+ Network: Network of IP addresses in the network (ie the network = 172.16.1.0

+ Nexthop: A port of the router’s ip on the road next to the destination network of the packet

At Router0, Network 172.16.1.0 Subnet Mask 255.255.255.0 destination; for this network to be Router0 to go through port F0 / 0 of Router1, which IP ports this IP address = 10.0.0.1. So one way we can command

Router0> en

Router0 # conf t

Router0 (config) # ip route 10.0.0.1 255.255.255.0 172.16.1.0

Similarly on Router1 to send the packet to the destination network is 192.168.1.0 subnet mask 255.255.255.0, they must go through the nexthop ports f0 / 0 of Router0 (which IP port is 10.0.0.2)

So we have configured on Router1:

Router1> en

Router1 # conf t

Router1 (config) # ip route 10.0.0.2 255.255.255.0 192.168.1.0

Note: We must be configured on all routers, the new Ping each other for routing packets must be off and on (send and receive)

It is located at the IP for the PC machine in the order shown in Figure 1

Method 2: Router (config) # ip route <Network_dich> <Subnet Mask of Network_dich> <exit Interface>

+ Exit Interface: Name of Packet exit ports in the router is configured for example f0 / 0, s0 / 0

On Router0 want to the destination network, the packet will be released from the port F0 / 0, not f0 / 1 of this router, so we ordered:

Router0 (config) # ip route 172.16.1.0 255.255.255.0 f0 / 0

Similarly we have command on Router1:

Router0 (config) # ip route 172.16.1.0 255.255.255.0 f0 / 0

Results:

With the PC and router ports set as shown we can ping from PC0 to all other PC on the LAN

Note: With the 2 above can not configure the network environment Multi Access as follows:

Configure static routing multi access static (Configuring Static Routing)

Figure 2: Diagram showing the multiple access environments (Multi Access)

So if you want to Router0 destination network is 172.16.1.0 that every exit port f0 / 0 on Router0 then the next packet switch can not know is through Router1 or Router2 here.
