00:00:40,840 --> 00:00:46,290
In this lab we’ll look at the topic of HSRP\n
9
00:00:46,289 --> 00:00:50,429
This applies regardless of what first hop\n
10
00:00:53,549 --> 00:01:00,470
Basically, HSRP and STP synchronization means\n
11
00:01:00,470 --> 00:01:06,030
bridge, and the HSRP standby should be the\n
12
00:01:06,030 --> 00:01:11,680
Why should the HSRP active and the STP root\n
13
00:01:11,680 --> 00:01:16,900
It’s to ensure that traffic from the end\n
14
00:01:19,150 --> 00:01:26,020
If the HSRP active router isn’t the STP\n
15
00:01:26,019 --> 00:01:31,408
not take the direct path to DSW1, it might\ntake a longer path.
16
00:01:31,409 --> 00:01:35,640
This isn’t a disaster, but it’s obviously\nnot ideal.
17
00:01:35,640 --> 00:01:40,829
Because STP works by finding the shortest\n
18
00:01:40,829 --> 00:01:46,140
router is synchronized with the STP root means\n
19
00:01:47,500 --> 00:01:54,340
In this lab, we’ll make DSW1 the HSRP active\n
20
00:01:54,340 --> 00:01:59,850
HSRP active and STP root for VLAN 20.
21
00:01:59,849 --> 00:02:06,429
Before configuring HSRP and STP, let’s check\n
22
00:02:10,699 --> 00:02:14,189
Nothing, so HSRP hasn’t been configured\nyet.
23
00:02:19,949 --> 00:02:27,289
DSW1 has a root port, G1/0/3 which is connected\n
24
00:02:37,159 --> 00:02:40,329
Now I’ll get right into configuring DSW1.
25
00:02:40,330 --> 00:02:44,630
CONF T. Let’s configure STP first.
26
00:02:44,629 --> 00:02:48,709
SPANNING-TREE VLAN 10 ROOT PRIMARY.
27
00:02:48,709 --> 00:02:53,949
That should make DSW1 the root for VLAN 10,\n
28
00:02:56,240 --> 00:02:58,890
SPANNING-TREE VLAN 20 ROOT SECONDARY.
29
00:02:58,889 --> 00:03:06,069
Okay, let’s check the status now, VLAN 10\n
30
00:03:09,449 --> 00:03:16,039
Great, DSW1 is the root now as it says up\n
31
00:03:21,370 --> 00:03:26,870
Now, because we haven’t configured DSW2\n
32
00:03:26,870 --> 00:03:33,750
made DSW1’s priority lower than DSW2’s\n
33
00:03:33,750 --> 00:03:41,139
That’s fine, after we configure DSW2 it\n
34
00:03:41,139 --> 00:03:47,828
Now let’s configure HSRP here on DSW1, for\nthe VLAN10 SVI first.
35
00:03:49,310 --> 00:03:54,870
I didn’t give any specifics in the description\n
36
00:04:02,250 --> 00:04:07,879
STANDBY 10 IP, and let’s make the default\ngateway .254.
37
00:04:09,848 --> 00:04:16,348
I’ll make DSW1’s priority higher than\nthe default 100 next.
38
00:04:20,019 --> 00:04:23,300
And enable preemption too, it’s good to\nhave.
39
00:04:29,728 --> 00:04:33,189
Let’s enable version 2 here too.
40
00:04:35,189 --> 00:04:38,968
And then the virtual IP, .254 again.
41
00:04:41,490 --> 00:04:49,759
Note that these HSRP group numbers don’t\n
42
00:04:49,759 --> 00:04:54,809
Okay, next I’ll make it’s priority lower\n
43
00:05:06,870 --> 00:05:11,139
Now I’ll do similar configurations on DSW2.
44
00:05:11,139 --> 00:05:16,848
CONF T. First, make it the secondary root\nof VLAN 10.
45
00:05:16,848 --> 00:05:20,668
SPANNING-TREE VLAN 10 ROOT SECONDARY.
46
00:05:20,668 --> 00:05:23,519
And the primary root for VLAN 20.
47
00:05:23,519 --> 00:05:26,188
SPANNING-TREE VLAN 20 ROOT PRIMARY.
48
00:05:26,189 --> 00:05:29,909
Let’s check the STP status now.
49
00:05:32,519 --> 00:05:36,389
DO SHOW SPANNING-TREE VLAN 20.
50
00:05:38,718 --> 00:05:42,430
And DSW1 should remain the root for VLAN 10.
51
00:05:45,360 --> 00:05:53,330
Perfect, DSW2’s root port is G1/0/3 which\nis connected to DSW1.
52
00:05:59,110 --> 00:06:01,809
First let’s make the version match.
53
00:06:03,918 --> 00:06:09,318
And then configure the same virtual IP, the\n.254 of the subnet.
54
00:06:14,079 --> 00:06:19,248
And let’s lower the priority here, even\n
55
00:06:23,028 --> 00:06:25,430
And I’ll enable preemption too.
56
00:06:27,019 --> 00:06:32,288
Okay, that’s all for VLAN 10, now VLAN 20.
57
00:06:52,718 --> 00:06:55,240
All of the configurations should be good now.
58
00:06:55,240 --> 00:07:01,718
Again, DSW1 should be active in VLAN 10 and\n
59
00:07:03,069 --> 00:07:06,658
Active in VLAN 20 and standby in VLAN 10.
60
00:07:06,658 --> 00:07:12,808
Let’s check first here on DSW2 if it’s\n
61
00:07:19,300 --> 00:07:26,020
The active is 10.0.10.1, which is DSW1, and\n
62
00:07:28,509 --> 00:07:32,699
The active is local and standby is 10.0.20.1,\nDSW1.
63
00:07:32,699 --> 00:07:41,179
So it all looks good here on DSW2, but let’s\n
64
00:07:42,869 --> 00:07:51,749
Okay, in VLAN 10 the active is local and DSW2\n
65
00:07:51,749 --> 00:07:57,499
So, we have configured both STP and HSRP as\nin the instructions.
66
00:07:57,499 --> 00:08:03,509
This ensures that hosts in VLAN 10 have a\n
67
00:08:03,509 --> 00:08:09,028
and hosts in VLAN 20 have a direct path to\n
68
00:08:09,028 --> 00:08:15,300
Synchronizing the STP and HSRP configurations\n
69
00:08:15,300 --> 00:08:19,918
Although to be honest I doubt you’ll be\n
70
00:08:19,918 --> 00:08:24,178
I always try to give you more information\n
71
00:08:24,178 --> 00:08:26,728
Okay, that’s all for this lab.
72
00:08:26,728 --> 00:08:35,750
Now let’s take a look at a lab in Boson\n
