Ace enter! Cisco s Static Route Configuration Issue! 10

The C segment of the given network segment.

0001 0001 (17) pc0

0001 0010 (18) pc1

0011 0001 (49) pc2

0011 0010 (50) pc3

0101 0001 (81) pc4

0101 0010 (82) pc5

A total of five network segments are required.

Analyzing the address of the PC by borrowing 4 bits can fully meet the needs of the network segment.

r0 f0 0011 【

s0 0001 【

r1 s0 0010 【

s1 0001 【

f0 0011 【

r2 s0 0010 【

f0 0011 【

Segment A between PC and R0 is.

CIDR block b between R0 and R1 is.

CIDR block C between R1, PC2, and PC3 is.

R is the segment d.

The network segment E between PC and R2 is.

The directly connected CIDR blocks of Router 0 are A and B

The direct CIDR blocks of Router 1 are b, c, and d

The direct CIDR blocks of Router 2 are D and E

Configure each configuration according to the address analyzed above.

Static route configuration.

router config mode.

IP Route Configure the default route.

It is also possible to configure static directly to 0.

#ip route

The focus of the experiment was on the division of IP addresses.

IP route is used on all three routes

Experiments can be done, but the real environment is not so engrossed hehe.

What exactly do you want?

Secondly, your SW, RT's specific IP address is given.

clock rate

ip route

The main thing is that these two commands are in nothing!

Static route configuration is a route method in which route items are manually configured rather than dynamically decided.

Unlike dynamic routing, static routing is fixed and does not change, even if the network conditions have changed or have been reconfigured. In general, static routes are added to the routing table by the network administrator one by one.

The advantage of using static routes is that the network security is highly confidential. Dynamic routing requires routers to frequently exchange their routing tables, and the analysis of routing tables can reveal information such as network topology and network addresses. Therefore, the network can also use static routing for security reasons.

It does not consume network bandwidth because static routes do not generate update traffic.

@静态路由.

Refers to the routing information that is manually configured by the network administrator.

The ip route command will add a static route to the routing table @ to indicate that ip route(-static) is a static route command that tells the router to mask the packets of this network segment to be sent through this address. (i.e., set it as a gateway) [ is the next hop address, and the whole command means that all packets sent to are sent to this address].

I'll give you a screenshot, so it seems convenient to explain the point, the static route of POOH is (assuming that the IP of POOH is.)

ip route

The first one is the local IP address in which the subnet mask is defined, and I should be optimistic, I correspond to 27 bits, and the one behind the left is written as the next hop of the inbound interface (I am hypothetical pooh to write static detigger).

Of course, you can also write it as a network segment mode, which is where you can also write it as (s0 interface) in the figure

ip route s0

ip route s0

I'm going to give you some extensions. (It seems to have become a CCIE occupational disease, hehe, if you don't want to see it, just see it).

LZ This problem is very classic, hehe, the static application is also quite extensive, and it can also solve the problem of irregular areas (tunnel keeps flipping), the reason is because the static AD of the cherry blossom is the smallest, and the priority is higher.

Let's take a look at the second edition of the second volume of the first volume of the second volume of Si Chennako, which is quite detailed.

**I found it casually from the top of the Roll Mess, but it's enough to explain the static configuration.

1.Cisco's S port is a WAN port, which can be transferred to RJ45, and FA is a LAN port and a Fast Ethernet port.

2.If you want to communicate, there are two ways, one is to borrow the mask, so it is in the same network segment, but the broadcast risk is relatively large; The second is to build two Jingtai routes on the router, and .

3.Small LANs should be relatively simple, set DHCP, route different network segments, and NAT it.

Oh, it's definitely not working, it's obviously not the same network segment as the above configuration command, (and your IP address above is not subnetized) you need to announce the network number to get through, only the subnet you said needs to be configured with a routing protocol, and your routing protocol version also supports the division of subnets, otherwise it won't pass!

Questions**:

Question Name: Static Route Configuration.

Duration: 40 minutes.

1. Operating conditions.

1) Three Cisco routers.

2) Each device is connected to the network.

2. Operation content.

If you have a network of several routers (router names R1, R2, and R3), configure each device so that they can communicate with each other. Here's how:

1) Configure the basic commands on each router separately as required:

The configured host names are r1, r2, and r3.

Disable DNS queries;

Set the clock to the current time;

Set the privileged password to Cisco;

Password encryption is properly enabled.

2) According to the requirements, configure the IP address and clock frequency on each router port to ensure that the direct connection port is unblocked;

The circles represent loopback interface 0 on R1, R2, and R3, and the clock frequency is set to 64000.

3) Create a static route on R1 to point to,,

Create a static route on r2 that points to, ;

Create a static route on r3 to point to,,

3. Operational requirements.

1) The basic configuration of the router is correct.

2) The IP address is configured correctly.

3) The static route is created correctly.
