WEBVTT 1 00:00.000 --> 00:01.880 We're here in this challenge. 2 00:01.880 --> 00:04.200 We really wanted to make sure we could identify 3 00:04.200 --> 00:07.800 when a property belongs to HSRP version 1 or version 2 4 00:07.800 --> 00:09.360 or VRRP. 5 00:09.360 --> 00:11.640 And yeah, there's version 2 and version 3 6 00:11.640 --> 00:14.520 but VRRP is largely the same between the two 7 00:14.520 --> 00:18.680 outside of IPv6 as well as the millisecond timers. 8 00:18.680 --> 00:22.240 So when break this down, 224.0.0.2, 9 00:22.240 --> 00:25.800 this is used by HSRP version 1. 10 00:25.800 --> 00:28.040 Remember, that's the all routers address. 11 00:28.040 --> 00:35.240 Dot 18, this is VRRP and Dot 102, this would be HSRP version 2. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 11 00:28.040 --> 00:35.240 Dot 18, this is VRRP and Dot 102, this would be HSRP version 2. 12 00:35.240 --> 00:38.000 The virtual max, try to make this a little bit tricky 13 00:38.000 --> 00:41.800 because if I just put X's in for the blank spots, 14 00:41.800 --> 00:44.760 then we could be able to tell which one was HSRP version 2 15 00:44.760 --> 00:47.840 because it supports more group IDs than the other two. 16 00:47.840 --> 00:51.640 But when we see 5E in there, that is going to tell us 17 00:51.640 --> 00:53.680 that it's VRRP. 18 00:53.680 --> 00:56.520 And then the 0C indicates that it's Cisco. 19 00:56.520 --> 01:00.920 So Cisco has that OUI, all zeros and then 0C. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 19 00:56.520 --> 01:00.920 So Cisco has that OUI, all zeros and then 0C. 20 01:00.920 --> 01:03.640 And then we just have to distinguish between the two. 21 01:03.640 --> 01:10.640 And so this first one, 07 AC, this would be HSRP version 1 22 01:10.640 --> 01:14.040 and the 9FF, meaning that the F99, 23 01:14.040 --> 01:17.000 that was actually representative of the group ID, 24 01:17.000 --> 01:20.360 this would be HSRP version 2. 25 01:20.360 --> 01:21.440 Configuration default. 26 01:21.440 --> 01:27.360 So preemption enabled, that is a VRRP conversation. 27 01:27.360 --> 01:30.920 If we want to enable preemption on HSRP, we can, WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 27 01:27.360 --> 01:30.920 If we want to enable preemption on HSRP, we can, 28 01:30.920 --> 01:32.680 but it does default. 29 01:32.680 --> 01:36.240 So our key here, it does default to being disabled with HSRP. 30 01:36.240 --> 01:38.280 Mill second timers, this is interesting 31 01:38.280 --> 01:42.040 because this was enabled with HSRP version 2, 32 01:42.040 --> 01:45.600 but also with VRRP version 3. 33 01:45.600 --> 01:48.200 So keep in mind that we don't have Mill second timers 34 01:48.200 --> 01:50.960 with VRRP version 2. 35 01:50.960 --> 01:54.160 Now lastly, with the roles, active and standby, 36 01:54.160 --> 01:58.720 this belongs to HSRP, both version 1 and version 2. 37 01:58.720 --> 02:03.640 Master backup, this is what we refer to VRRP's devices as. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 37 01:58.720 --> 02:03.640 Master backup, this is what we refer to VRRP's devices as. 38 02:03.640 --> 02:07.120 And lastly, listen, also goes with HSRP. 39 02:07.120 --> 02:09.760 If we have more than two nodes with VRRP, 40 02:09.760 --> 02:13.160 they're just all known as backup nodes at that point. 41 02:13.160 --> 02:14.600 So again, we just want to make sure 42 02:14.600 --> 02:17.120 that we understand FHRP operation, 43 02:17.120 --> 02:19.840 including the usage of virtual MAC addresses. 44 02:19.840 --> 02:22.040 By the end of the skill and before we move on, 45 02:22.040 --> 02:27.160 we should be able to identify which protocol is it used 46 02:27.160 --> 02:29.200 based on a particular virtual MAC address. 47 02:29.200 --> 02:31.320 We should understand the concept of failover WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000 47 02:29.200 --> 02:31.320 We should understand the concept of failover 48 02:31.320 --> 02:33.400 and using preemption to failback. 49 02:33.400 --> 02:36.560 And just generally speaking, our FHRP purposes 50 02:36.560 --> 02:39.360 and communications leveraging multicast addresses, 51 02:39.360 --> 02:41.840 and which addresses should be leveraged 52 02:41.840 --> 02:44.640 or would be leveraged with every protocol. 53 02:44.640 --> 02:45.960 I hope this has been informative for you, 54 02:45.960 --> 02:48.440 and I'd like to thank you for viewing.
