MPLS two vrf inter-communication
Hi all,
Customer requirement
1- Location near to PE1 should use PE1 to access internet
2- Location near to PE2 (i.e CE3) use PE2 to access internet
3- CE1,CE2 and CE3 should communicate to each other
4- Incase PE2-CE2 link goes down CE3 should access internet from PE1
What we offered
1- We have created two vrf one is for PE1 (MESH-1) and One is for PE1 (MESH-2) (First Two requirement fulfilled)
2- Done intervrf communication between PE1 and PE2 (3rd requirement meet)
3- Now customer is announcing default from CE1 with AS path contain one AS
default from CE2 with AS path contain three AS (It is not path prepend)
In above situation default from PE1 became best and CE2 uses PE1 to access internet which customer do not want
We have tried to insert default route from PE1 by decreasing local preference to 50 towards PE2
with extcommunity RT but in this scenario CE4 starts accessing internet via PE2
Is here any wayout for this ?
Let me know if any more iput is required
Thanks in advance
Mahesh
Hi,
To be sure PE2 always prefer the default route received from CE2, you should increase the weight. As this attribute will never be transmitted it will not influence PE1 route selection and it will choose the one with the shortest AS PATH.
If CE3 and CE4 are directly connected to PE2 and PE1 then you should be fine. If not, I would configure PE1 and PE2 to export those default routes with different community. Remote PEs will set different LP based on the community during the import process.

Hi all, this is my post, I need to integrate two VRFs, that is, a Banking corporation will expand its operations and will integrate with a financial group. These two, are customers of the same service provider, and represent each a different VRF. Now I need to integrate them into one. The Question...How can I do to solve the problem of same LAN Subnets..?...Same WAN Subnes..?..Do I need to necessarily change the IP scheme of one of the two VRFs before I can proceed with the integartion?
Hector,
This is no different from merging two networks outside of the VRF context. You either need to renumber the overlapping networks or use NAT (or even double NAT in some cases).

Inter Communication between portlets getting error ed out
Hi ,
I am trying to create inter communication with 2 portlets . I created 2 portlets and created a global parameter(params1) which i used in both the portlets. My requirement is that i need to enter a value in first portlet and by clicking a button in first portlet, i should be able to display the same value in my second portlet. I created them but was getting an error when i am clicking on the button in first portlet.

Thank you,
Sashank P.hello vipin,
how did you start your MAM? are you using the -app option?
from the log, it seems that you have an auto-login enabled.
if you ran your MI from NWDS, try removing the debug
options -logon:<user>:<password>
how did you ran your MI btw?

Dynamic Configuration for two file adapters communication channels
Hello Experts!!!!!!
In one of the interface in my landscape, I am using two file adapters for creating two files with different names and at two different destination on F.T.P.
However the receiver service for both the communication channel are same.
In message mapping I am using multi mapping to create two files out a single message.
Now i have a requirement of changing file path and file name using dynamic configuration for both the comm channel.
When i doing dynamic coniguration for both the comm. channel. My interface is creating two files but with same name and on same destination which is set for second communication channel through dynamic configuration.
Here, I guess the second dynamic configuration is over writing the first dynamic configuration and hence creating two files with same name and at same destination.
Please suggest, if separate dynamic configuration for separate communication channel of same receiver service can be done?
Thanks & Regards,
AmolThanks for your prompt responses!!!!!
Is there any way, By which in dynamic configuration I can find out the communication channel name and then change its parameter.
I mean if iam using say comm. channel A and B.
Then in dynamic configuration for A, I will first take communication channel A by calling it and then change its path/file name.
and then do samething for comm. channel B in its dynamic conf.
Regards,
Amol -
Our WAN cloud will be a mesh between 3 campuses. Our provider will provide Layer 2 transport services, 1Gbps, FIFO. At each campus I will be running 2821 for WAN edge.
All services will be converged onto this WAN, Voice, Video, Data.
At each campus runs 3750 or 6513 as Campus Core peering 2821's. Each campus will be running VRF-Lite. My goal is to become the MPLS service provider for the college. The 2821's are the PE devices and the Campus Core's are the CE devices. Example, Voice will have it's own VRF at each respective site, each vrf will learn routes from other voice vrf's from the 2821's. Currently the 2821's peer each other iBGP. I want to be able to allocate portions of bandwidth (1Gb) for each VRF on the WAN and queue the traffic within each VRF.Hi,
You need to configure normal QoS, remark the triple play traffic (data voice video) in ingress interface on the switch and implement queuing and bandwidth reservation out the egress interface of the router.

What can be done to avoid this?Using SAML tokens (policies are there in OWSM) you should be able to propagate the security credentials-

Exchange of initial key for two way encrypted communication
Hello all,
I think the following question has to do with my lack of knowledge of cryptography and will be happy for any pointers you might provide.
I am trying to encrypt socket communication between client/server. I have decided to use AES from the SUNJCE. I don't want to store a static key on the client as that would pose a threat(decompilation). And I don't want to send the key to the client as that would defeat the whole purpose of encryting the communication (the key might get sniffed over the network).
I have a feeling there is a better way but since I am new to crytpography I am a bit lost. Can anybody tell me if there is a standard (best-practice) way of doing this.
Thanks in advance for your help.
depeupleur_For anyone interested in AES for flash check this code
out:
http://www.codecta.com.br/rijndael.zip
Wow - that is impressive.
I now have a different problem, i can protect the data
being transmitted between server and a legitimate
client but since the connection is done through
internet and i don't know who the potential users are
how can i make sure the client that connects in the
first place is not a rogue client looking to replace a
proper client and trying to determine the
communication protocols and encryption mechanisms?You really do need to read up on how this stuff works. If "Applied Crypto" is too much, there's another book, "Practical Cryptography", by Ferguson and Schneier, that covers the topic pretty readably as well. (The first section, anyway - it gets pretty dense after that...)
In general - if you're going to worry about the identity of the client, you can set up your server to require client-side certificates. Explaining how certificates work is more than a forum-message thing.
Note that, in The Land of Crypto, you must assume that The Bad Guy knows everything about your communications protocols except for the key. If your security relies on hiding them, or your specific encryption algorithm, then you're pretty much toast.
Too right, i won't even pretend that i could write any
crypto code. (unless it is for my little son to
decrypt as a game)It's actually a very interesting field. I would not call myself a cryptographer by any stretch of the imagination - I'm just an educated user of crypto libraries. With a little research, you can be one too! ;)
Good luck,

Two ear file communicating with each other
HI,
I have one doubt,
I Have two ear files (two webservices actually) deployed succesfully in the same application server (Weblogic7.0). Let us say them a.ear and b.ear
In a.ear there are class say A.class and B.class. In B.java file there is a staic HashMap which stores some object based on some id. Also in B.java there is static method which takes the id as a parameter and return the corrospojnding object stored in the static hasmap.
In b.ear file there class say B.class and C.class. Note that this ear file has its own copy of B.class file. In C.java file i create an object (though i dont need create being it a static method) of B.java and calls the static object passing it the id and expecting it that it will return me the object stored in the Hashmap. it returns me null though it has the objects stored for that id.
Is it because both ear files has their own copy of B.class. but i though that that they are running in the same jvm in application server so it should not be a problem. if this is the reason then my problem will be solved if i put them in same ear file.
Can anybody put his insights into his experiences and lemme know what is the cause of problem and solution and for my knowledge why it is happening.
Best Regards,
Akhil NagpalYou're right that the two have different copies of the class. This is because the EJB container uses a different classloader for different applications, to prevent statics clashing with each other and other related security reasons.
Usually if you want to communicate from one to the other, you would use the EJB mechanism itself. The JNDI names should be global (from simple tests I did in the past, this seems to be the case) so that one application can look up an EJB from the other. -
Signed applets, JOGL, inter communication
Hi,
I am trying to display two applets and to make them communicate in a same page :
- First one is an applet instantiated with JOGLAppletLauncher class from JOGL API. It is named "SampleApplet_001" in web page.
- Second one is a simple button that sends a command to the first one with such code :
Applet applet = ((JOGLAppletLauncher)getAppletContext().getApplet("SampleApplet_001")).getSubApplet();
if (applet != null) {
}But when clicking on button, a class cast exception occurs like : java.lang.ClassCastException: com.sun.opengl.util.JOGLAppletLauncher cannot be cast to com.sun.opengl.util.JOGLAppletLauncher.
This is a typical class loader issue but in that case, I have carefully checked that :
- codebase and archive parameters are identical for both applets : codebase is an explicit URL and archive parameter is a list of jars,
- web caches were empty,
- used java plug-in version is the latest one,
- it is not related to a browser version. It fails for IE7 or Firefox 2.0.
Has anyone encountered such issue ?
Thanks.
SteveI am having the same issue with my applet. Please let me know if you have a work around/fix.

VLAN inter communication - almost there!
I have been working on this for a few days. Im almost there!
I want my Management Vlan to be able to ping Computers in the DMZ vlan. Im not sure if its NAT issue or ACL issue.
Specifically im ping from 192.168.0.5(management comp) to 10.10.10.5(DMZ comp)
Packet tracer shows no errors and says it should be working.
I pick up a weird error in the log that says: Routing failed to locate next hop for ICMP from Management:192.168.0.5/256 to inside:10.10.10.5/0
Why is it saying the 10.10.10.5 is on the inside, when its on the DMZ?

I think the problem most likely is the NAT configuration.
Is there a specific reason you are using Dynamic PAT from one interface to another ("nat" and "global" between local interfaces)? If this is not required I would suggest a different type of configuration for the whole NAT if you want to try it out. This would involve removing some of the existing configurations and will naturally effect the network operation while you do it.
Removing old ones
no global (inside) 1 interface
no global (DMZ) 1 interface
no global (Management) 1 interface
no static (inside,Management) 0.0.0.0 0.0.0.0 netmask 0.0.0.0
no static (inside,DMZ) 0.0.0.0 0.0.0.0 netmask 0.0.0.0
Adding new configurations
Existing ones
!global (outside) 1 interface
!nat (inside) 1 0.0.0.0 0.0.0.0

And naturally attach ACLs to interfaces to control traffic if needed
Hope this helps

Today or over the weekend, for no reason that I can tell, all of the links in my email (just checked that too) and my RSS feeds no longer link to FireFox. The following error appeared in Outlook "General Failure. URL:... An error occured in sending the command to the application." I'm not sure if it's Outlook or Firefox but this just happened for no reason that I could tell and I'm not computer savvy enough to go in to Outlook and figure all this out. It's worked with no issue for well over a year. The only recent change to Firefox I've made is to add an Amazon wish list toolbar...which I'm not even sure how to delete if that's the issue...but I'm not sure that it didn't work after installing that add-on. I've made no recent changes to Outlook (2007).
Just to recap, this is a collection of ports I have collected over time for people who needed this information when setting up the HP ePrint app so that they could view their email from within the app. I am certain other applications also need this information. Although lengthy, I could not find a more comprehensive place to retrieve this information. Feel free to post additional information, faulty information, or other related topics below as this is simply a collection of data and it would be practically impossible to test all of them. Thank you!
Don't forgot to say thanks by giving "Kudos" if I helped solve your problem.

Reg : Two WD components communication.
hi ,
I have created 2 Wd components Flights and Bookings.
Flights WD component is using Bookings component as USED component .
Iam calling 2nd WD Bookings component in an external window.
METHOD onactioncall .
DATA : lv_url TYPE string.
CALL METHOD cl_wd_utilities=>construct_wd_url
EXPORTING
application_name = 'Z187442_ALV1'
IMPORTING
out_absolute_url = lv_url.
DATA lo_window_manager TYPE REF TO if_wd_window_manager.
DATA lo_api_component TYPE REF TO if_wd_component.
DATA lo_window TYPE REF TO if_wd_window.
lo_api_component = wd_comp_controller->wd_get_api( ).
lo_window_manager = lo_api_component->get_window_manager( ).
CALL METHOD lo_window_manager->create_external_window
EXPORTING
url = lv_url
RECEIVING
window = lo_window.
lo_window->open( ).
ENDMETHOD.
here my req is : I want the selected values from first component FLIGHTS .....to be exported to second component BOOKINGS...SO that I can write a select statement based on values imported from 1st component .
Select * from sbbok into table it_bookings where carrid = (here carrid value should be the one which is selected from the first application lead index)
Connid =(here connid value should be the one which is selected from the first application lead index)
any ideas ?
regards
ArjunHi Arjun,
I had created my application so that up on lead selection in the 1st application the corresponding SFLIGHT details would get passed to the 2nd WDA and it would display the relevant details from SBOOK. I created an action for the lead selection & within this method am appending the CARRID, CONNID & FLDATE values to the 2nd applications URL.
CALL METHOD cl_wd_utilities=>construct_wd_url
EXPORTING
application_name = 'Z187442_MAIN1_SUBCOMPONEN'
IMPORTING
out_absolute_url = lv_url.
concatenate lv_url '?' 'CARRID=' wa_data-carrid '&'
'CONNID=' wa_data-connid '&'
'FLDATE=' wa_data-fldate into lv_url.
So now when you call the 2nd application even the required parameters would have been passed on to it.
Now within the 2nd application you would have to receive these passed parameters and code your SELECT so that it would fetch the desired data and bind it to your context node.
1) Go to the inbound plug (which should be DEFAULT generally unless you have renamed it) & double click on it
2) Within the event handler method HANDLEDEFAULT put the desired coding like shown below
METHOD handledefault .
DATA: lr_node TYPE REF TO if_wd_context_node,
lt_data TYPE ig_componentcontroller=>elements_sbook.
select * from sbook into corresponding fields of table lt_data
where carrid = carrid and connid = connid and fldate = fldate.
lr_node = wd_context->get_child_node( name = 'SBOOK' ).
lr_node->bind_table( new_items = lt_data ).
ENDMETHOD.
I have tried it out this way and its working fine. But yes you would be able to see the values being passed in the URLu2026

Displaying a page in a particular region
Hi
We have several tabs for different pages. One of our tabs is "Inofrmation and resources" within this page we have a region on the left handside with a list of departments within the company. I'd like to be able to open a new page within the right hand side region of this page depending on which department you click on.
I've tried to create seperate pages but when these open we loose the tabs at the top. I dont want to be recreating the tabs on all the different pages we create.
So my question is how can I display a page within a particular region depending on which link is clicked?Hi Neil,
How about having two portlets inter-communicating with each other ... Did you have a look at the Site Indexing Portlet available on the Portal Integration Solutions site (http://www.oracle.com/technology/products/ias/portal/point.html) ?
thanks,

We have a CE router connected to PE router. The CE router is connected via 2 links to the PE router, because we need to create two VRFs on the PE for the traffic coming from the CE to separate the traffic, so we have one vrf per link. We are running OSPF between CE and PE.. Now we need to further separate the traffic up to the CE, so Im thinking of using the VRF lite on the CE.. Can MPLS work with the VRF lite, and how to map the VRF lite VRFs on the CE to the MPLS VPN on the PE?
Is there any config examples?
Thanks in advanceVRF Lite and MPLS-VPN act independently so they can work independently. And there is no specific need for mapping. If link is for VRF A on PE so you can make it part of vrf A in CE as well. Both VRFs are independent of each other.
