0:00:16	Our next feature we have here in RIP is how
0:00:22	Now, we looked at before the difference between IP
0:00:29	where IP Default Network can be used
0:00:33	in order to take an advertisement
0:00:38	that is not directly connected and tagged
0:00:44	though typically, that information was only used
0:00:51	So, with RIP, technically, you could
0:00:54	but there's a much easier way to do this
0:00:55	with simply the Default Information
0:01:02	Now, when we do this, the default route will be
0:01:08	and we can control with a route map both
0:01:14	and a condition that will control whether the
0:01:20	which is considered conditional default routing.
0:01:25	So here in our topology,
0:01:32	that has the connections
0:01:37	router 6 and switch 1.
0:01:41	So, under the process of switch 1,
0:01:48	that...
0:01:50	under router RIP,
0:01:54	Default-Information Originate.
0:02:00	Then, look at the routing tables of
0:02:05	If we Show IP Route RIP.
0:02:08	We see that the default route
0:02:14	So, pretty straightforward implementation,
0:02:18	to advertise the default route every
0:02:22	If we were to look at router 6,
0:02:26	we should see likewise the same
0:02:32	We see that the default is
0:02:36	To conditionally advertise this,
0:02:39	we could specify that the default route
0:02:45	In which case, we are
0:02:50	under the route map that matches the specified
0:02:56	So, if we create a route
0:03:03	we'll say, Route Map Default.
0:03:07	It will be Permit 10 automatically.
0:03:09	If we set the interface to our VLAN 79,
0:03:17	Then, under the routing process,
0:03:20	we'll say, Default-Information Originate,
0:03:24	but we're doing this with the
0:03:30	In this case now, if we look at switch 3,
0:03:34	we should see that nothing is changed. If we look
0:03:38	which is 0.0.0.0/0, we see that
0:03:45	but router 3 and router 6,
0:03:49	we can see, they're no longer
0:03:55	So, although the command is at global
0:04:01	we can control what interfaces the
0:04:06	Now, notice also this does not remove any
0:04:11	So, if we look at the full
0:04:15	all of the other dynamically learned RIP routes
0:04:23	Now, the other option for
0:04:27	is typically in a case where we have
0:04:32	And we want to control where the default is originated
0:04:39	So, let's say that we have
0:04:44	that are connecting to two
0:04:52	So, router 1 is connecting to ISP 1.
0:04:56	Router 2 is connecting to ISP 2.
0:05:02	Then, we have our
0:05:08	The goal of this type of design would be
0:05:14	and for router 2 to advertise a default route,
0:05:19	but we would want to prevent the case
0:05:21	that when router 1 looses its connectivity
0:05:27	then, the default route
0:05:30	Otherwise, router 1 should
0:05:34	that it cannot actually deliver
0:05:38	And this is what our condition is going
0:05:42	Now, we are gonna be matching just
0:05:47	but this prefix could be in the
0:05:51	it could be a connected interface, it could
0:05:56	which means that we have a lot of flexibility
0:06:03	So, let's do this from the
0:06:09	We'll say that we want to
0:06:12	and it's gonna go out all
0:06:15	But I wanna make sure that I actually
0:06:20	before I originate the route.
0:06:24	So first, let's just do the normal
0:06:29	Under the process, we'll say,
0:06:40	If we look at router 5 and Show
0:06:48	we see that we're learning
0:06:54	Now, the problem in
0:06:57	would be the case that we discussed
0:07:03	is not a good indication of whether we actually
0:07:09	Because between router 4 and bakbone 3, there
0:07:16	So, if BB3 looses its connection
0:07:19	this is not going to update the line
0:07:25	So, we could with the condition look
0:07:30	which is the 204.12.10.0 network,
0:07:35	but in the case that router 4's link
0:07:41	that would not be a good indication whether
0:07:47	But since we can define whatever
0:07:50	we can combine this
0:07:54	with other features like the enhanced object
0:07:59	where we can tie them to static routes,
0:08:03	which would then be conditionally installed in
0:08:08	So, let's say now that on router 4,
0:08:11	we have some sort of
0:08:15	We'll say that we have a route
0:08:26	This goes to null zero.
0:08:29	This 169.254 address base, this is
0:08:37	So, it is non-routable address base.
0:08:41	Now, under the route map,
0:08:43	we're going to match a prefix list
0:08:47	that says, "If this route isn't a table,
0:08:53	So, we'll say, IP Prefix List.
0:08:58	which is 169.254.0.1/32.
0:09:05	Then, under the route map,
0:09:10	we'll say, "If the prefix list..."
0:09:14	So, Match IP Address
0:09:20	If this route is in the table,
0:09:25	So now, under the RIP process,
0:09:29	Default-Information Originate.
0:09:33	And we'll say, "We're gonna advertise
0:09:40	So, the route map is
0:09:48	If we look at the result
0:09:51	we should ideally see that the default
0:09:57	If I go to router 4 and now
0:10:02	we ideally should see that the default
0:10:09	So, we'll take out the place holder.
0:10:12	So, not the prefix list. The...
0:10:17	actual route.
0:10:19	So now, the route is removed.
0:10:23	Which then should mean, the default
0:10:33	So now, we could take this
0:10:38	We'll say, "Now, I'm going to put a
0:10:42	that determines whether that place holder
0:10:47	And we'll do this based on the IP SLA.
0:10:50	So, on router 4, at this point, we should
0:10:56	which is 204.12.10.254.
0:11:00	I now wanna create a condition
0:11:03	that says, "In the case that ICMP
0:11:08	I will remove the place holder route",
0:11:11	Which in turn causes the
0:11:15	which means that 4 will man.
0:11:20	So, if there's another possible exit
0:11:25	then, we would prefer their default information as
0:11:33	So, then, our next step would be
0:11:37	We'll say, "For SLA instance 1,
0:11:40	the type of monitoring will be
0:11:45	So, as we see, there's a lot of different
0:11:49	but ICMP is just a good indication
0:11:55	I'm gonna ping BB3.
0:12:00	And the source IP address is gonna
0:12:08	The frequency will be every 5 seconds
0:12:15	So, timeout of 2 seconds.
0:12:26	Now, we need to start the
0:12:33	Or IP SLA Schedule 1.
0:12:37	We want to start this now,
0:12:42	forever.
0:12:46	If we look at the Show IP
0:12:54	let's say, Show IP SLA...
0:12:59	Show IP SLA...
0:13:04	Statistics for number 1.
0:13:08	So, right now, the return code is "OK", which is good.
0:13:15	Next, we need to define an enhanced object,
0:13:22	So, we have a tracked object,
0:13:25	We're gonna track an IP SLA instance,
0:13:31	Okay, I'll just leave the defaults here.
0:13:33	Then, as the very last step, I'll reinstall the
0:13:40	but now, this is gonna call the
0:13:47	What we should now see is
0:13:55	or more actually, if the tracked object.
0:14:00	It says the return code is "OK".
0:14:04	It means that the static
0:14:06	which then means the
0:14:10	So, if we look at router 5, we can
0:14:13	That's what we want.
0:14:16	Now, we're going to break connectivity
0:14:23	But where I'm gona do this is somewhere in the network
0:14:30	So, on switch 3, if I look at
0:14:34	I have the switch port Fast Ethernet 0/24
0:14:42	So, on this interface, I'm gonna
0:14:48	Now, if we look at router 4 and
0:14:52	we know that shutting the
0:14:56	is not going to update the line
0:15:01	Because it's unrelated to router 4,
0:15:06	However, since we
0:15:10	it means that the SLA
0:15:13	which in turn means that
0:15:17	which then, in turn means
0:15:22	Which means the route
0:15:25	which then finally means that router 4
0:15:32	So, it's a lot of steps in the logic that
0:15:36	but it's a really interesting implementation that you can use
0:15:44	Because in most designs, you would
0:15:48	to the remote autonomous systems
0:15:52	but since we now have the enhanced
0:15:57	there's a lot of interesting things
0:16:01	So, if we look at the full
0:16:04	this would be including the
0:16:09	the route map, the prefix list,
0:16:16	originate.
0:16:24	So again, router 4 is saying...
0:16:26	"I'm gonna use this SLA instance
0:16:31	If I may be able to ping them,
0:16:35	If tracked object 2 is up, it means that
0:16:41	which means that this prefix list
0:16:46	which then means that we
0:16:52	But if any of these individual pieces fall
0:16:58	or if we loose ICMP reachability,
0:17:00	then, we see router 4 withdraws
0:17:07	Once the switch port of BB3 comes back,
0:17:10	eventually router 4 is going to regain...
0:17:14	its connectivity to BB3.
0:17:18	Okay, which is immediate there.
0:17:21	Which then means that router 5 should
0:17:30	The only issue with this is compared to other solutions
0:17:37	is that unless you tweak the timers,
0:17:39	it's gonna be slower the converge
0:17:42	than some of the other solutions.
0:17:44	So, if high availability is a
0:17:47	this may not...
0:17:50	this may not be viable.
0:17:53	But we should see eventually here that 5
0:18:22	Which now it does.
0:18:24	So, it's actually a combination
0:18:29	plus the other timers that are going
0:18:33	plus the SLA, then, the negligible internal time that
0:18:42	and then withdraw the default information.
