Routing process

Hi,
While I am debuging ICMP traffic originated from a router ( Debug ip packet details) it is showing packets routed via FIB and reply is showing as routed via RIB .is it means ICMP packet originating from the router is CEF switched ? if it does then whether the CEF switched packet will show in the debug output ?.Documents showing that only process switched packet can be debugged .
one more doubt regarding the routing process
documents stating that the routing process is actually consist of three processes 1.routing 2.switching 3.encapsulation
so regardless of every switching methods (Process ,Fast or CEF ) router is doing routing table lookup in the first process (Routing)
thanks

The IP Routing Process for VLAN's?

I have the CCNA Study Guide third edition. Chapter five, page 254 has a description of the ip routing process. It descripes the ip routing process using two nodes on different subnets and a router.
We've recently deployed VLAN's, so I'm asking if I replace the router with a switch in the description, if the principles would still apply? I'm also asking if someone knows of a link that describes the ip routing process when using a VLAN? I'm looking for documentation that's similar to what's in the book, but modernized.
tia

I do not have the book but i will try to help:
Switches dont do inter-vlan routing (Unless you are using a layer 3 switch) so if you are have different Vlans configured on your switch and want them to comunicate each other without a router you cant.
If you have a router the same principles apply to normal routing, remember that VLANS are just a way of dividing your clients, so your VLANS configured on your subinterfaces will appear directly connected on your ip route table. For example:
VLAN 10: 192.168.10.0
VLAN 20: 192.168.20.0
VLAN 30: 192.168.30.0
You have vlan 10 and 20 locally on a lan interface (They will be directly connected on your ip route) but vlan 30 is reachable thru a serial interface (ppp or frame relay) you would use:
ip route 192.168.30.0 255.255.255.0 serialx/x

2 - way routing process in an ESB

Hi !
I want a 2-way routing process in an ESB .
My requirement is there is two table say Emp and Company .
I will select some data from Emp and after some transformation I will insert those to data into Company table .
When I am using poll then it is working fine but when I am trying to use select and insert query then router only accept select wsdl not the insert wsdl .
Help me regarding this

Hi,
I am afraid that there is no way to have two routing nodes in one flow. But you can use service call to get same job done.

6513 ACL List ION Routing Process

Hello everyone I have a question about ION Routing Process that seems to show up on the 6513 cisco switch.
Ok question, when I do a show access-list Test-ACL
It will show me Test-ACL list then right after that with ION Routing Process the next line starts with all of the ACL lists that are on the device.
We have two 6513 and they both do this but when i check out two 6509 they dont do this.
Also check on 3750e too dont do this
Can anyone explain this to me ?

Craig
What you are asking for can be done but it will be a bit tedious. You describe having 20 entries in the topology table and you want to control which one gets placed into the routing table. To do that you can either make the composite metric of the one entry more attractive or you can make the composite metric of the other 19 less attractive.
When you use an offset list you add to the metric of an entry. It will not make any entry be more attractive but it can make other entries less attractive. So you could configure an offset list identifying the route in question and apply some offset (100 should work for example). Then you would need to apply this offset to the 19 neighbors who are advertising the route.

Two route-processes for same vrf on a PE

Hi
Is it possible to have two route processes, for example eigrp and ospf, for the same vrf on a PE router.
The situation would be, two customer sites on one PE, one site is running EIGRP and the other one OSPF
Thanks for your replies
michael

You should be able to use any combination of supported IGP (ospf, eigrp, rip, static) or BGP between the different the PE and the different CEs belonging to the same VRF.
Hope this helps,

Can CRM 2011 email router process digitally signed emails?

Hi there,
Please can you tell em is the CRM 2011 email router is able to process digitally signed emails, as our just seems to ignore them.
Its annoying as you can track the email manually, but not through the email router at the moment.
Many thanks

Hi Bartosz,
Can i ask if you ever found a way forward with this...?
I think i have a similar issue with signed emails not being processed.

ICM7 Install - RouterA process on RoggerB

I'm having an issue for an ICM upgrade from 6 through 7.0c SR4 to 7.5.x. As part of the upgrade process a RoggerA and RoggerB are built based on ICM7.0c using an EDMT import of the 6.0 database and a copyof the ICM registry key tree from each respective source Rogger i.e. apply RoggerA 6.0 registry tree to new tech refresh RoggerA 7.0 and apply RoggerB 6.0 registry tree to RoggerB 7.0. This is the process described in the upgrade guide.
However, when RoggerB is installed and rebooted after the ICM7.0c install, it attempts to run both RouterB AND RouterA on the same server. It suddenly seems to think it is now RouterA as well as RouterB. The registry now shows a new tree for RouterA, icmsetup shows RouterA and the process attempt to run RouterA. The real RouterA has already been installed, is running and is connected via bopth public and private network.
I've trawled the release notes for ICM 7.0c through to SR4 but can't see a mention of this issue which would be a pretty major problem.
We have fixed the issue by deleting the RouterA registry tree before rebooting the server and also deleting the entry via icmsetup, which should mean we can then move on to upgrade to ICM7.5. However, I'm concerned that this isn't a good starting point for a new 7.5 build so would like to understand why this issue is occuring.
Is there a patch that I am missing here?
Jed

Thought it worth a follow up on this.
The custonmer has been running fine with the fix process they went through, however I still wanted to understand why this happened. After some TAC assistance they pointed me at the following bug which is exactly this issue ... dman annoying that I couldn't find this bug with standard search terms.
http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCsh70013
At least the problem is understood and I know the ICM build is fine to work from,

Upgrade Actiontec router - process?

I have the Rev A version of the actiontec router. For the sake of argument, lets say I get my hands on a Rev F. Is it a complicated process to replace one with the other? Can I simply unplug the old and plug in the new, or am I going to have to undertake some fancy configuring? Thanks in Advance.
Solved!
Go to Solution.

Its quite simple.
There are 2 easy ways.
1. Fast. Log into the current router. release the IP address, disconnect and then connect the new. Done
2. Slow, unplug the first router. leave everything disconnected for at least 2 hours then connect new router. Done. I would disconnect when I go to bed and then next morning connect the new.

Reg approval routing process

Hi,
I am following this note to define the approval process for the items to be uploaded.
It is
http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/OTN_CONTENT/MAINPAGE/PUBLISH_CONTMGMT/TECHNOTE_APPR_OVRW.HTML
I defined the approval routing at page group and page level and gave the recepient as one of administrative users.
I made one user having manage items with approval privilege.When I login as this user upload item in a region under some tab then the item gets added.It should not.
When I login as an administrative user and check my notifications portlet there is not item pending approval.
Therefore this approval process is not working.
Could u pls help me in that.
Thanx
-Vipul

If the tabs have their own security settings that user should not be able to see them. Check that the user doesn't also have View privilege on the page group - that might be overriding the tab privileges.
For updated documentation on the approval feature, please refer to the new User's Guide. This version is currently in beta for the upcoming 9.0.4 release, but applies and is generally accurate for the 9.0.2.6 release.

[OSB] SOAP Message Body Deleted in Routing Process

Hello Folks,
I'm using Oracle Services Bus 11g and I have the following scenario:
A Business Services that is a client of a WebService. This WebService has an operation that return in its Soap Message a field with special characters (an encripted password).
So, I've created an Proxy Service that route the request message to above business service, but when the message returned by Business service is routing back to Proxy Service the body of the message is deleted.
Checking out the trace of the call, it says "Body was deleted" ! And so the message is returned by Proxy service without body !
I suspected that problem is something about encoding !
Someone could help me resolve this problem ?
Thanks in advanced!

Hi,
I am facing some similar issues with OSB 10gR3 where the Message body gets deleted and i get empty soap body as response when i make continuous calls to a business service without any time delay between the calls.
Though surprisingly i get the correct response from the business service for the first time but only on consecutive calls without any time delay between two calls i get empty soap body. Later if i try to call the business service leaving a gap of 15 sec after my first call, i get the correct response.
I initially thought it might be a problem with the business service itself but when i try to make continuous calls to the Business service without any timedelay directly from SOAPUI , I am getting correct response everytime.
Hence this seems to be a problem only when i invoke the business service via the OSB proxy and thsi deletes the response body wehn i make continuous calls.Not sure whether this is a bug with OSB or encoding issues.
Pls help me to know if this has anything to do with the caching or any setting in OSB server.
Thank you

Routing Process in Change Number !

Hi Folks,
I am new to the PP module.So, I want know what is Routing ? How it can be created ?
And what all the dependencies one has to look for while creating ?
At the same time I have one issue regarding CN (Change Number ).
1. My Client is having one CN with the N number of routings associated with it.
2. I want to change effectivity of one routing among these N to current date.
3. Also I want to change another routing effectivity among these N to specific date.
4. After doing 2 & 3 I am updating the CN i.e. Change Number.
But when I update the CN all the other routings are also getting updated, which i do not want to happen.If I do not update the CN , changes made to the routings are not getting updated.
So, if any one has a answer for the above , please let me know.
Thanks & Regards,
R V Kulkarni.

Hi,
BGP Router process is in charge to determine the best path and processes any route "churn". It also sends and receives routes, establishes peers, and interacts with the routing information base (RIB).
(http://www.cisco.com/c/en/us/support/docs/ip/border-gateway-protocol-bgp/107615-highcpu-bgp.html)
So I suggest to check what make this process working hard. Depending on that you can choose what to do: bgp dampening (if you have many changes in advertisement received form a neighbor), tuning timer (if neighbor is flapping), using peer-group / update-groups to reduce the amount of job your BGP process has to do to process updates etc...

Routing and DNS processes stop - IOS 15.1(4)M9

Hi all,
I have an 1841 router acting as ADSL gateway. It has maxed out RAM and HWIC-1ADSL module installed.
Some time after upgrade from IOS 15.1(4)M6 to IOS 15.1(4)M9 the router started to behave somewhat strange. Every 3-5 days routing process stops, that is if I do "sh run" I get "no ip routing" in configuration which wasn't there before. It appears that config was not edited by anyone either. On top of that router stops resolving DNS. A simple reboot fixes the DNS issue.
I get following in the logs (sh log):
003801: Jan 2 05:39:13.569 AEST: %SYS-3-CPUHOG: Task is running for (2004)msecs, more than (2000)msecs (1/0),process = DNS Server.

Has anybody experienced something like this?
Is this a 15.1(4)M9 issue?

Hi Alex,
Based on the above logs Spurious access is an attempt by Cisco IOS software to access memory in a restricted location. An example of system log output for a spurious access is shown below.
000059: Jan 3 12:27:36.189 AEST: %ALIGN-3-SPURIOUS: Spurious memory access made at 0x631586D4z reading 0x1C
000060: Jan 3 12:27:36.189 AEST: %ALIGN-3-TRACE: -Traceback= 0x631586D4z 0x631768E8z 0x63176998z 0x63177590z 0x631C2438z 0x631C2658z 0x62FE3ED0z 0x62FE4258z
Cause
A spurious access occurs when a process attempts to read from the lowest 16 KB region of memory. This portion of memory is reserved and should never be accessed. A read operation to this region of memory is usually caused when a nonexisting value is returned to a function in the software, or in other words, when a null pointer is passed to a function.
Cisco IOS Software Handling
Depending on the platform, Cisco IOS software handles spurious accesses differently. On platforms where this is possible, the Cisco IOS software code handles these invalid accesses by returning a value of zero and recording the event. If this is not supported on the platform, then the router will crash with a SegV error. Since any spurious access is inappropriate, spurious accesses always point to a bug.
You may also want to have a look at below document.
http://www.cisco.com/c/en/us/support/docs/ios-nx-os-software/ios-software-releases-120-mainline/15103-spuraccess.html
In my opinion I think you are hitting a bug here.
HTH,
Nikhil
