R4 (config-if) #int Lo0

R4 (config-if) #ip add 4.4.4.4 255.255.255.0

Lab Step 2:RIP Routing advertisement

R1 Configuration:

R1 (config) #router rip// start rip process

R1 (config-router) #network 1.1.1.1 //network command advertises each interface route, note RIPv1 is classfull< /c10> Protocol

R1 (config-router) # network 192.168.12.0

R2 Configuration:

R2 (config-if) #router RIP

R2 (config-router) #network 192.168.12.0

R2 (config-router) #network 192.168.23.0

R3 Configuration:

R3 (config) #router rip

R3 (config-router) #network 192.168.23.0

R3 (config-router) #network 192.168.34.0

R4 Configuration:

R4 (config-if) #router RIP

R4 (config-router) #network 192.168.34.0

R4 (config-router) #netwo 4.4.4.4

Experimental commissioning:

R1#showip rout// View R1 routing Table

C 192.168.12.0/24 is directly connected, serial1/0//r1 Direct-connect route via s1/0 interface

1.0.0.0/24 is subnetted, 1 subnets

C 1.1.1.0 is directly connected, Loopback0// ring-back direct-Connect routing

R 4.0.0.0/8 [120/1] via 192.168.12.2,00:00:21, serial1/0 // learn from RIP to class A Routing

R 192.168.23.0/24 [120/1] via 192.168.12.2, 00:00:21, serial1/0// Learn class C routing through RIP

R 192.168.34.0/24 [120/1] via 192.168.12.2, 00:00:21, serial1/0// Learn class C routing through RIP

The meaning of the routing entry "4.0.0.0/8 [120/1] via 192.168.12.2, 00:00:21, serial1/0" is as follows:

① R: Routing entries are learned through RIP routing protocols;

② 4.0.0.0/8: Destination network;

③ : The default administrative distance of RIP routing protocol;

④1: measure value, 1 hops from router R1 to network 4.0.0.0/8 ;// The problem comes, how can only 1 jump?

⑤ 192.168.12.2: Next hop address;//IP address of neighboring router interface

⑥ 00:00:03: The next update also has a (30-3) seconds;

⑦ serial1/0: The interface ofthis router R1 that receives the route entry .

r1#show IP Protocols // view R1 Routing Protocol

Routing Protocol is "RIP"// router is running on the routing protocol is RIP

Outgoing update filter list for all interfaces are not set// No filter lists in out direction

Incoming Update filter list for all interfaces are not set// No filter lists in direction

Sending updates every seconds, next due in the seconds// update period is a second, and the next update has a nanosecond

Invalid after-seconds, hold-down, flushed after// invalidation, suppression and refresh time

Redistributing:rip// only runs rip Protocol, no other protocol redistribution comes in

Default version Control:send version 1, receive any version// send route update for Release 1 , and receive routing updates for this version 1

Interface Send Recv triggered RIP key-chain

serial1/0 1 1 2

Loopback0 1 1 2

The above three lines show the interfaces that run the RIP protocol, and the version of RIP routing updates that can be received and sent

Automatic network summarization is in effect//rip routing protocol turns on auto-summarization by default

Maximum path:4//rip Routing protocol can support 4 equivalent paths, maximum 6

Routing for Networks:

1.0.0.0

192.168.12.0

The above three lines indicate the network that RIP advertises

Routing Information Sources:

Gateway Distance Last Update

192.168.12.2 120 00:00:13

Distance: (default is 120)

the above three lines indicate the routing information source, where:

Gateway: The interface address of the router that learns the routing information, that is, the next hop address

Distance: Managing Distances

Last update: How long before the update occurred

Distance: (default is 120)

default administrative distance is 120

"Note" To prevent updates from synchronizing , RIP sends updates with 15% errors, that is, the range of cycles that actually send updates is

25.5-30 seconds. // The teacher mentioned the point of attention during the class.

r1#debug IP Rip // This command can view the dynamic update process for RIP routing protocols.

There's a problem here?

" Flash Update " Flash Update (flash update) means that when a measure of a path on the network changes, the router immediately issues updates, regardless of whether the cycle of regular routing information updates is reached.

Learning experience:

1. How the routing protocol initiates the process;

2. Router RIP, network *.*.*.* Operation command and its function;

3. The meaning of the routing table;
   

4. Debug commands: show IP route, show IP protocols, debug IP RIP, these commands I often forget.
