1
00:00:11,680 --> 00:00:12,640
So here's router 1

2
00:00:15,750 --> 00:00:21,490
show IP Interface Brief shows us the IP addresses configured on the router.

3
00:00:22,280 --> 00:00:28,170
Here's the loopback interface, here's the IP address on gigabit 0/0/0.

4
00:00:29,430 --> 00:00:33,110
So the first thing we need to do is configure an exclusion range.

5
00:00:34,590 --> 00:00:42,630
So IP DHCP excluded-address 10.1.1.1 to 10.1.1.100.

6
00:00:44,000 --> 00:00:49,910
The next thing we need to do is configure a pool called PC.

7
00:00:51,250 --> 00:00:57,640
The network to use is 10.1.1.0 with a subnet mask of /24.

8
00:00:59,150 --> 00:01:08,300
We then need to configure a default router or default gateway of 10.1.1.254, because

9
00:01:08,720 --> 00:01:11,390
that's the IP address of router 1.

10
00:01:13,510 --> 00:01:20,310
So the default route will be that DNS server will be the router and that looks good.

11
00:01:21,040 --> 00:01:29,470
So Show Run there's our exclusion range and there's our DHCP pool show IP DHCP binding.

12
00:01:30,570 --> 00:01:36,270
Our client has already been allocated an IP address, 10.1.1.101.

13
00:01:37,230 --> 00:01:42,090
So let's confirm that by opening up a command prompt

14
00:01:43,380 --> 00:01:44,550
IP config.

15
00:01:46,530 --> 00:01:56,010
There's the IP address of the PC, there's the subnet mask, there's the default gateway, can the PC

16
00:01:56,010 --> 00:01:57,980
ping router 1?

17
00:01:57,990 --> 00:01:58,920
Yes, it can.

18
00:01:59,490 --> 00:02:01,830
Can it ping the loop back of router 1?

19
00:02:02,130 --> 00:02:03,210
Yes, it can.

20
00:02:04,260 --> 00:02:04,950
And

21
00:02:06,870 --> 00:02:15,570
to confirm that show IP interface brief, there's the loopback of router 1, and the PC can ping

22
00:02:15,750 --> 00:02:17,130
the loopback router 1.

23
00:02:18,150 --> 00:02:20,470
Can the router ping the PC?

24
00:02:20,550 --> 00:02:21,510
Yes, it can.

25
00:02:22,350 --> 00:02:25,530
So we've successfully configured DHCP

26
00:02:26,560 --> 00:02:36,520
on router 1 and tested that the PC gets an IP address via DHCP and that the PC can ping the loopback

27
00:02:36,520 --> 00:02:37,690
of router 1.

28
00:02:38,670 --> 00:02:42,610
That was a very basic DHCP lab in the next labs.

29
00:02:42,630 --> 00:02:44,100
It gets more complicated.
