1
00:00:00,000 --> 00:00:00,680

2
00:00:00,680 --> 00:00:03,500
It's pretty amazing to see
a dynamic routing protocol

3
00:00:03,500 --> 00:00:04,085
at work.

4
00:00:04,085 --> 00:00:05,960
So here's what we're
going to do this Nugget.

5
00:00:05,960 --> 00:00:08,960
We're going to demonstrate
three different dynamic routing

6
00:00:08,960 --> 00:00:11,545
protocols on our
topology right here.

7
00:00:11,545 --> 00:00:12,920
And, currently,
the only networks

8
00:00:12,920 --> 00:00:14,630
that the routers know
about are the ones

9
00:00:14,630 --> 00:00:16,100
that they're directly
connected to.

10
00:00:16,100 --> 00:00:19,110
So there's R1, which is
directly connected networks.

11
00:00:19,110 --> 00:00:22,220
Here's R2, and then here's R2.

12
00:00:22,220 --> 00:00:23,060
Fantastic.

13
00:00:23,060 --> 00:00:24,657
Let's go ahead and add RIP.

14
00:00:24,657 --> 00:00:26,990
What this does-- it goes into
configuration mode on each

15
00:00:26,990 --> 00:00:29,870
router, tells the router we
want to run the RIP routing

16
00:00:29,870 --> 00:00:30,530
process--

17
00:00:30,530 --> 00:00:32,420
and specifically version 2--

18
00:00:32,420 --> 00:00:33,920
that we do not
want to do any type

19
00:00:33,920 --> 00:00:37,130
of automatic summarization,
and we want any interfaces that

20
00:00:37,130 --> 00:00:39,830
begin with the IP
address of 10 anything

21
00:00:39,830 --> 00:00:43,180
to be included as part of
this RIP routing process.

22
00:00:43,180 --> 00:00:46,310
So we'll send that script
to all three routers.

23
00:00:46,310 --> 00:00:48,870
So here in R1, it's
learned four routes.

24
00:00:48,870 --> 00:00:52,920
It learned about the 10.4,
10.5, 10.7, and 10.8 networks.

25
00:00:52,920 --> 00:00:55,880
Here on router 2, it's
learned about the 10.1, 2, 6,

26
00:00:55,880 --> 00:00:57,470
and 8 networks.

27
00:00:57,470 --> 00:01:00,140
And on router 3, it's learned
about the 10.1, 2, 3, 4,

28
00:01:00,140 --> 00:01:01,400
and 5 networks.

29
00:01:01,400 --> 00:01:02,169
Fantastic.

30
00:01:02,169 --> 00:01:03,710
Next, we're going
to send the command

31
00:01:03,710 --> 00:01:08,060
to remove the RIP router process
and then put in the EIGRP.

32
00:01:08,060 --> 00:01:10,850
We're also telling EIGRP to
include the interfaces that

33
00:01:10,850 --> 00:01:12,360
begin with 10.

34
00:01:12,360 --> 00:01:15,140
So we'll send that out to
all three routers, as well.

35
00:01:15,140 --> 00:01:16,880
And you'll notice we have
some neighbor adjacencies that

36
00:01:16,880 --> 00:01:17,421
have come up.

37
00:01:17,421 --> 00:01:18,140
Fantastic.

38
00:01:18,140 --> 00:01:19,340
And let's take a look
at the routing table

39
00:01:19,340 --> 00:01:20,810
on all three routers, as well.

40
00:01:20,810 --> 00:01:24,410
And R1, via EIGRP, has
now learned dynamically

41
00:01:24,410 --> 00:01:25,610
these networks.

42
00:01:25,610 --> 00:01:28,670
R2 has learned these
networks, and R3

43
00:01:28,670 --> 00:01:30,800
has learned these networks.

44
00:01:30,800 --> 00:01:33,305
So, next, we're going to
remove EIGRP routing process,

45
00:01:33,305 --> 00:01:37,130
and in its place, we're going
to put in OSPF process ID 1.

46
00:01:37,130 --> 00:01:39,590
And this network statement
effectively, in Cisco world,

47
00:01:39,590 --> 00:01:42,140
says, we want to
include every interface

48
00:01:42,140 --> 00:01:45,740
that the router's running
as part of this OSPF routing

49
00:01:45,740 --> 00:01:46,530
process.

50
00:01:46,530 --> 00:01:49,030
So with that in place, we'll
send that to all three routers,

51
00:01:49,030 --> 00:01:50,950
as well.

52
00:01:50,950 --> 00:01:53,730
Next, we have some messages
regarding the OSPF neighbor

53
00:01:53,730 --> 00:01:54,930
[INAUDIBLE] being set up.

54
00:01:54,930 --> 00:01:57,390
All three routers know how
to reach the other networks

55
00:01:57,390 --> 00:01:59,520
in our topology, this time
because they learned it

56
00:01:59,520 --> 00:02:02,160
dynamically via the
OSPF routing protocol.

57
00:02:02,160 --> 00:02:04,550
So here's router 1.

58
00:02:04,550 --> 00:02:06,530
Here's router 2.

59
00:02:06,530 --> 00:02:08,924
And here's router 3.

60
00:02:08,924 --> 00:02:10,340
In this Nugget,
we've demonstrated

61
00:02:10,340 --> 00:02:15,800
three dynamic routing protocols,
RIP version 2, EIGRP, and OSPF.

62
00:02:15,800 --> 00:02:17,990
I hope this has been
informative for you,

63
00:02:17,990 --> 00:02:21,490
and I'd like to thank
you for viewing.

64
