We're here in this challenge.
We really wanted to make sure we could identify
when a property belongs to HSRP version 1 or version 2
or VRRP.
And yeah, there's version 2 and version 3
but VRRP is largely the same between the two
outside of IPv6 as well as the millisecond timers.
So when break this down, 224.0.0.2,
this is used by HSRP version 1.
Remember, that's the all routers address.
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
Dot 18, this is VRRP and Dot 102, this would be HSRP version 2.
The virtual max, try to make this a little bit tricky
because if I just put X's in for the blank spots,
then we could be able to tell which one was HSRP version 2
because it supports more group IDs than the other two.
But when we see 5E in there, that is going to tell us
that it's VRRP.
And then the 0C indicates that it's Cisco.
So Cisco has that OUI, all zeros and then 0C. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
So Cisco has that OUI, all zeros and then 0C.
And then we just have to distinguish between the two.
And so this first one, 07 AC, this would be HSRP version 1
and the 9FF, meaning that the F99,
that was actually representative of the group ID,
this would be HSRP version 2.
Configuration default.
So preemption enabled, that is a VRRP conversation.
If we want to enable preemption on HSRP, we can, WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
If we want to enable preemption on HSRP, we can,
but it does default.
So our key here, it does default to being disabled with HSRP.
Mill second timers, this is interesting
because this was enabled with HSRP version 2,
but also with VRRP version 3.
So keep in mind that we don't have Mill second timers
with VRRP version 2.
Now lastly, with the roles, active and standby,
this belongs to HSRP, both version 1 and version 2.
Master backup, this is what we refer to VRRP's devices as. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
Master backup, this is what we refer to VRRP's devices as.
And lastly, listen, also goes with HSRP.
If we have more than two nodes with VRRP,
they're just all known as backup nodes at that point.
So again, we just want to make sure
that we understand FHRP operation,
including the usage of virtual MAC addresses.
By the end of the skill and before we move on,
we should be able to identify which protocol is it used
based on a particular virtual MAC address.
We should understand the concept of failover WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000
We should understand the concept of failover
and using preemption to failback.
And just generally speaking, our FHRP purposes
and communications leveraging multicast addresses,
and which addresses should be leveraged
or would be leveraged with every protocol.
I hope this has been informative for you,
and I'd like to thank you for viewing.
