Hi,
I'm currently preparing my CCNP TShoot certification exam. I have some difficulties to understand the command output of "show ip route profile" command. I know to produce any output the : "ip route profile" as to be enable on the router before.
I read TShoot officiasl certification guide for my studdyies, about this command the author was'nt written a lot ! Because I was'nt understand I had looking an different explanation on the net. I found the following http://packetlife.net/blog/2010/jan/4/routing-table-profiling/
by this :
I understand in the following output :
R1# show ip route profile
IP routing table change statistics:
Frequency of changes in a 5 second sampling interval
-------------------------------------------------------------
Change/ Fwd-path Prefix Nexthop Pathcount Prefix
interval change add change change refresh
-------------------------------------------------------------
0 96 96 96 96 96
1 0 0 0 0 0
2 0 0 0 0 0
3 0 0 0 0 0
4 0 0 0 0 0
5 0 0 0 0 0
10 0 0 0 0 0
15 0 0 0 0 0output truncated
the number under "Fwd-path change" as to be accumulation of prefix-add (96), next-hop change (96), and pathcount change (96) statistics. where 288 why is it written 96 ? or because a new prefixe was add to the router this also trigged "next hop change" and "path count" counter this is also logical because this we do not have 288 in the fisrt column, the text was supposed "accumulation of prefix-add, next-hop change, and pathcount change statistics" for different routes.
This output was probebly done on a router which as reload after the ip route profile was enable because in the first time interval 96 prefix were add to the router.
I do not understanding at all the following sentences :
We can see that all five events have a value of 96 in the 0 row. This tells us two things: first, route profiling has been enabled for the last 8 minutes (96 * 5 seconds per interval = 480 seconds / 60 = 8 minutes). Second, since all columns only have an entry in the 0 row, this tells us that no changes have occurred; in other words, the routing table has remained stable.
The next let me confusing :
Assume R2 loses its connection to the 10.0.23.0/30 network. This will be reflected as a change in the next update of the profile:
in the interval 0 the number as changed and Fwd-path change is less that Nexthop change were it supposed to be an accoculation of the statistic. what's append between 96 justed previously and now 172 ? only one network as been removed ? in the second line we have an addition of an prefix which is supposed to be correspond to the network change (because it's highlight)
the rest of the text is no more clear to me.... but maybe after explanation about the above, will be easier to me to understand ?
Thanks a lot !

Hi,
The first colum under Change/Interval is the number of events that occured in every 5 sec interval.
Forwardin path change is the aggregate of other 3 attributes only when there is a change occured in the routing table. So you should not consider the Zero change/interval (first row with 0 change/interval) because there is no change happened in that interval. If you take the other two outputs, where there is 1 change/interval, then you can find forwarding path change is the sum of other three attributes.
In the doc, when the network is stable, there is no changes been happening for the routing entries in the routing table. This means Zero events been detected every 5 sec interval. Thats why in line to 0 row - the counters are increased. So the value of 96 means 96 intervals (interval of 5 sec each) i.e. 96*5/8=8 mins. So for 8 mins there is no change in the routing table.
172 indicates that around 15 mins (172*5=860/60) there have been no changes in routing table. After 172nd interval, there is one change in the routing table that is R2 loses 10.0.23.0/24, so the corresponding change/interval i.e. 1 change in this interval is reflected in the output under Prefix Add and Fwd-path-change.
When the same netowrk (10.0.23.0/24) is available then in another interval it is reflected under Path Count change. But now Fwd-path change is set to 2 which is the accumulation of Prefix add and Pathcount change attributes. You can see that the values in 0 row is increased which means it took some time for the lost network to be up i.e. 10.0.23.0/24.
Hope the above explanation is clear.
thanks

Hi Arun,
I was long to response to you because I was still confused after your explanation, to try to understand I had but back on my own Cisco lab try test this command to try to understand something....

PXR4#
I had remark the first line is always increment by one each second or around this but defenitely less than 5 sec.
when you says : "This means Zero events been detected every 5 sec interval. Thats why in line to 0 row - the counters are increased." I do not understand this, I hope this line not increment if not changed in routing table.... Also, this counter do not reset after any changed in the routing table (network add or removed)
in this calculation "So the value of 96 means 96 intervals (interval of 5 sec each) i.e. 96*5/8=8 mins. So for 8 mins there is no change in the routing table." where did you took the first number 8, it's may looklike evident for most people but I did not seen the evidence....
When you saying : "172 indicates that around 15 mins (172*5=860/60) there have been no changes in routing table." what about the number 1 in the row below, or the number 4 in my output test ?
Thanks a lot for your help on this !

Hi,
Let me try to put in a different way of interpreting "show ip route profile" output
The output shows the number of events/interval with respect to the attributes defined in the top row. Every interval if there is no change in the routing table, then 0 events/interval counter will keep on incrementing. If there is a change in the routing table i.e. 1 route is changed in that interval then a counter in 1 change/interval (2nd row) will be incremented that too only for the particular attribute.
1. Every 5 sec interval if it detects zero changes then the corresponding counter under the corresponding row value will increase. Thats the reason if there is no change in the routing table you get to see the counters in Zero change/interval keep increasing. You can observe this when the network is stable and i checked its increasing every 5 seconds. This counters will not be reset when there is a change.
2. This is a typo from me. 96*8/60=8 mins. Its actually divided by 60 seconds to get the value in minutes.
3. When you look again to the initial URL that you referred, the change in the routing table happened only after 172 intervals meaning close to 15 minutes there were no changes in the routing table and network was stable. The change happened after 172nd interval. Even in your recent output, the network was stable for 27 intervals then only you did a change. And whatever change happens the corresponding change/interval counter will be incrementing. In your case, there are 4 intervals where 1 change/interval happened. Thats the reason you can see value of 4 in the line straight to 1 change/interval.

Hi !
is it possible yopu made a typo again in equation : 96*8/60=8 mins ? where we should read 96*5/60=8 mins. where the number 5 refer to the 5 minutes intervals ?
On my router, the line 0 was incrementing around each seconds or maybe second and half but definitely not at 5 seconds intervals... One thing I do not understand is why can use be sure in the following output a change as occur after 32 time interval if I provide only that one :
PXR4#sh ip rout pr

from previous output from my personnal lab. because I do not see any difference between that one and the one provide in that one :
PXR4#sh ip rout pr

except the second one was on the 102 interval I was only provide that one you may supposed a changed as occur after 102 times intervals where it's not true the change was occur after 32 times intervals...
I think when I will understand this the rest will be easier to understand for me about this output.....
Thanks a lot for your help !
