1
00:00:16,180 --> 00:00:22,810
In this lab, we're going to configure default gateways and ensure that the devices in the network can

2
00:00:22,810 --> 00:00:23,740
ping one another.

3
00:00:24,520 --> 00:00:29,900
To do that, we need to configure and optimize HSRP or hot standby routing protocol.

4
00:00:30,400 --> 00:00:35,170
We're going to enable EIGRP on the core switches and ISR router.

5
00:00:35,890 --> 00:00:42,300
We're going to configure the PCs and the server with IP addresses as shown here.

6
00:00:42,760 --> 00:00:47,130
And then we're going to make sure that the PCs can oing each other as well as the server.

7
00:00:47,710 --> 00:00:52,180
And we need to verify connectivity between the switches and server and PCs.

8
00:00:53,230 --> 00:01:01,870
So as an example, this PC in VLAN 1 should be able to ping PC 2,PC three, the server and the

9
00:01:01,870 --> 00:01:10,580
access switches and the router, once this lab is completed. Can you complete this lab yourself? Download

10
00:01:10,600 --> 00:01:13,790
the attached packet tracer file and try it.

11
00:01:14,260 --> 00:01:18,670
It's not easy, but see if you can do it and get it working yourself.

12
00:01:19,240 --> 00:01:22,660
You need to be able to do this for the CCNA exam.
