Editor to share with you the example analysis of RIP dynamic routing protocol configuration, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's learn about it!

Dynamic routing

Dynamic routing and static routing is a relative concept. The biggest difference between dynamic routing and static routing is that dynamic routing does not need to add routes manually. Routes can learn from each other and can be adjusted automatically according to the changes of links and nodes.

Dynamic routing principles:

1. Timely exchange of routing information between routers (usually every 30 seconds)

2. The router processes the collected routing information into a routing table according to a certain routing algorithm (different dynamic routing protocol algorithms), which can be consulted by the router when forwarding IP packets.

The common dynamic routing protocols on the Internet at present:

1. RIP protocol (the protocol demonstrated in this article)

RIP protocol is the first widely used protocol, which is a routing protocol based on hop count, which is mainly suitable for small and medium-sized networks with low overhead.

2. OSPF protocol

OSPF protocol is an internal gateway protocol, which is mainly used to make routing decisions in a single autonomous system.

3. IS-IS protocol

IS-IS protocol is a dynamic routing protocol designed by ISO for connectionless network protocols.

4. BGP protocol

BGP is the only protocol used to handle networks the size of the Internet, and it is also the only protocol that can properly handle multiplex connections between unrelated routing domains.

Configuration and Verification of RIP

1. Start the RIP process

Router (config) # router rip

2. The main network number is declared

Router (config-router) # network network-number

3. View the routing table

Router#show ip route

4. View the configuration of the routing protocol

Router#show ip protocols

The difference between v1 and v2 versions of RIP protocol

Practical experiment of RIP dynamic routing protocol: the first step is to establish a complete topology diagram

Two PCs

PC1:192.168.10.24/24

PC2:192.168.20.20/24

Three routers

R2

F0/0:192.168.10.1/24

F0/1:12.10.1.2/22

R1

F0/0:12.20.1.2/22

F0/1:12.10.2.2/22

R3

F0/0:12.20.2.3/22

F0/1:192.168.20.1/24

Specific experimental topology diagram:

Step 2, set up directly connected routes for each router

First, configure the R2 route that connects to PC1

Enter: config terminal// to enter global mode

Enter: interface fastethernet0/0// enters f0ram 0 interface mode

Enter: ip address 192.168.10.1 255.255.255.0 / add IP address and subnet mask

Enter: no shut// to open

Input: interface fastethernet0/1

Input: ip address 12.10.1.2 255.255.252.0

Input: no shut

Input: end// returns to user mode

Enter: show ip route// to view the routing table

(two directly connected routes should already be included)

The next step is to set up the R1 router in the middle

Enter: config terminal// to enter global mode

Input: interface fastethernet0/1// enters f0ram 1 interface mode

Enter: ip address 12.10.2.2 255.255.252.0 / add IP address and subnet mask

Enter: no shut// to open

Input: interface fastethernet0/0

Input: ip address 12.20.1.2 255.255.252.0

Input: no shut

Input: end// returns to user mode

Enter: show ip route// to view the routing table

(two directly connected routes should already be included)

Finally, set up for the R3 router connected to the PC2

Enter: config terminal// to enter global mode

Enter: interface fastethernet0/0// enters f0ram 0 interface mode

Enter: ip address 12.20.2.3 255.255.252.0 / add IP address and subnet mask

Enter: no shut// to open

Input: interface fastethernet0/1

Input: ip address 192.168.20.1 255.255.255.0

Input: no shut

Input: end// returns to user mode

Enter: show ip route// to view the routing table

(two directly connected routes should already be included)

The third step is to configure IP addresses for two PCs

PC1

Enter: ip 192.168.10.20 192.168.10.1ax / set IP address and gateway address

PC2

Input: ip 192.168.20.20 192.168.20.1ax / set IP address and gateway address

At this point, although IP has been configured, it is not actually possible to interconnect PC1 and PC2.

The reason is that we did not configure the RIP protocol, so let's start the configuration of the RIP protocol.

Step one, enter R2.

Enter: config terminal// to enter global mode

Enter: router rip / / to start the RIP process

Enter: version 2max / use v2 version (see V1 and V2 differences above for reasons)

Enter: no auto-summary// turns off automatic subnet summarization

Input: network 192.168.10.0

Enter: network 12.10.0.0amp / declare two network segments directly connected to yourself

Step two, enter R1.

Enter: config terminal// to enter global mode

Enter: router rip / / to start the RIP process

Input: version 2max / use v2 version

Enter: no auto-summary// turns off automatic subnet summarization

Input: network 12.10.0.0

Enter: network 12.20.0.0amp / declare two network segments directly connected to yourself

Step 3, enter R3

Enter: config terminal// to enter global mode

Enter: router rip / / to start the RIP process

Input: version 2max / use v2 version

Enter: no auto-summary// turns off automatic subnet summarization

Input: network 12.20.0.0

Input: network 192.168.20.0 / declare two network segments directly connected to yourself

Step 4, return to R2 to view the latest routing table

Enter: end / / return to user mode

Enter: show ip route / / View routing table

(at this point, the beginning of R in the routing table is obtained through autonomous learning of multicast communication between routes.)

Similarly, this is true in the routing tables of both R1 and R3

After all the RIP routing protocols have been configured, test the interconnection between PC1 and PC2 again. The answer is yes:
