1 00:00:00,417 --> 00:00:04,707 In the previous section, we already learn about static routing. 2 00:00:05,083 --> 00:00:10,205 The disadvantages of static routing is when our network is dynamic. 3 00:00:11,028 --> 00:00:18,289 Every time we add new router to our network, we will need to add static routing configuration on all router. 4 00:00:19,123 --> 00:00:25,629 Let’s say we already have 100 router, and then we add 1 new router, 5 00:00:25,975 --> 00:00:34,105 so we will need to add static routing configuration on all router, which is 101 routers. 6 00:00:35,001 --> 00:00:42,323 This is why we will learn about dynamic routing in this section. If we use dynamic routing, 7 00:00:42,323 --> 00:00:49,242 when we add 1 new router, we just need to add configuration on the new router and the neighbor. 8 00:00:49,857 --> 00:00:56,751 So let’s say we have 100 router, and then add 1 new router, so we just need 9 00:00:56,751 --> 00:01:03,493 to add routing configuration on 2 router, which is the new router and the neighbor. 10 00:01:04,389 --> 00:01:09,485 Okay let’s just start, we will create a topology with 2 router 11 00:01:09,485 --> 00:01:15,000 first to learn about dynamic routing. Let’s import 2 router, 12 00:01:18,000 --> 00:01:26,133 let’s change the name, this is router 1 and this is router 2. 13 00:01:26,845 --> 00:01:32,457 Then let’s connecting this 2 router. Let’s also import 2 pc. 14 00:01:36,000 --> 00:01:42,415 pc 1 will be connected to router 1, and pc 2 will be connected to router 2. 15 00:01:43,113 --> 00:01:48,000 Let’s also change the name of the pc, this is pc 2 16 00:01:49,495 --> 00:02:00,509 and this is pc 1. Now let’s connecting pc 1 to router 1 and pc 2 to router 2. 17 00:02:03,067 --> 00:02:10,223 For the ip addressing, here will be 10.10.10.1/24, 18 00:02:14,003 --> 00:02:18,407 router 2 will be 10.10.10.2/24, 19 00:02:18,991 --> 00:02:29,911 router 1 that connected to pc 1 will be 192.168.1.1/24, and pc 1 will be 192.168.1.2, 20 00:02:31,697 --> 00:02:42,509 router 2 connected to pc 2 will be 192.168.2.1/24 and pc 2 will be 192.168.2.2. 21 00:02:43,561 --> 00:02:48,000 Now let’s configure the ip address on all router and pc. 22 00:02:48,873 --> 00:02:51,076 Let’s start with router1, no, enable, configure terminal, let’s start with fa0/0, 23 00:02:55,394 --> 00:03:07,511 no, enable, configure terminal, let’s start with fa0/0, so interface fa0/0, 24 00:03:07,888 --> 00:03:16,595 no shutdown, ip address 10.10.10.2 255.255.255.0, 25 00:03:17,457 --> 00:03:21,508 Next let’s configure fa0/1, 26 00:03:22,164 --> 00:03:32,660 so interface fa0/1, ip address 192.168.1.1 255.255.255.0. 27 00:03:33,873 --> 00:03:38,774 Okay done for router 1, next let’s configure router 2, 28 00:03:40,462 --> 00:03:58,275 no, enable, configure terminal, let’s start with fa0/0, so interface fa0/0, no shutdown, ip address 10.10.10.2 255.255.255.0, 29 00:03:58,959 --> 00:04:20,808 Next let’s configure fa0/1, interface fa0/1, no shutdown, ip address 192.168.2.1 255.255.255.0. Okay now we have done on router2. 30 00:04:21,645 --> 00:04:30,290 But we can see here that the interface of router 1 is still red, we forget to no shutdown on fa0/1. 31 00:04:36,977 --> 00:04:44,505 Okay now the light is green. Let’s check the ip address, do show ip interface brief. 32 00:04:46,013 --> 00:04:54,111 Okay here we can see that the ip address of fa0/0 is 10.10.10.1, this is correct, 33 00:04:54,111 --> 00:04:57,559 and fa0/1 is also correct. 34 00:04:58,441 --> 00:05:07,121 Let’s also check on router 2, do show ip interface brief, okay here the ip address is also correct. 35 00:05:07,693 --> 00:05:14,717 Now let’s configure the ip address of pc 1 and pc 2. Let’s start with pc 1, 36 00:05:17,335 --> 00:05:25,235 the ip address is 192.168.1.2, and the gateway is 192.168.1.1. 37 00:05:25,968 --> 00:05:27,000 Pc 2, 38 00:05:30,661 --> 00:05:38,203 the ip address is 192.168.2.2 and the gateway is 192.168.2.1. 39 00:05:39,217 --> 00:05:44,498 Okay now we have done configuring ip address on all router and pc. 40 00:05:44,897 --> 00:05:50,599 but for now, pc 1 should not be able to communicate with pc 2. 41 00:05:51,481 --> 00:05:57,869 Why? Because the table routing in router 1 and router 2 is not complete yet. 42 00:05:58,681 --> 00:06:05,309 Let’s write the routing table, on router 1 should have 2 network, 43 00:06:05,909 --> 00:06:20,481 first, 10.10.10.0/24 that connected to fa0/0, and 192.168.1.0/24 that connected to fa0/1. 44 00:06:23,631 --> 00:06:28,519 Let’s check it, do show ip route, 45 00:06:29,120 --> 00:06:35,577 here we can see that router 1 have 2 network in the routing table, as our calculation. 46 00:06:37,495 --> 00:06:42,489 Let’s also write the routing table on router 2, the first is 47 00:06:42,489 --> 00:06:56,623 10.10.10.0/24 that connected to fa0/0, and then 192.168.2.0/24 that connected to fa0/1. 48 00:06:59,151 --> 00:07:09,128 Let’s verify it, do show ip route, here we can see that router 2 have 2 network in the routing table. 49 00:07:09,603 --> 00:07:14,481 So now pc 1 and pc 2 should not able to communicate each others. 50 00:07:15,000 --> 00:07:18,971 In the next video, we are going to configure dynamic routing, 51 00:07:19,565 --> 00:07:23,239 so pc 1 will able to communicate with pc 2. 52 00:07:23,791 --> 00:07:26,142 I think enough for this video 53 00:07:26,142 --> 00:07:29,840 Thank you for watching and see you on the next video.
