2017-03-03 10:02:00 -0700 asked a question Boron BGP add route not working

I followed the boron BGP user guide and could establish a session with my juniper router. After adding it the the application group I tried pushing a route to the router (and i had this working in 0.4) but this route never show up. Not even in the outgoing RIB a trace file on the router also showed me that ODL does not even try to send it. Any hints what I might be doing wrong, welcome.

2016-06-19 05:48:30 -0700 asked a question How do I make data persistent on Disk

Hi,

so I wrote my own application to push flows. It has an RPC definition (restconf calls work) and I did define a registry in the YANG File that I use to write to. Using RESTCONF Calls (or the YANG-UI) I see data is written there.

However if I stop and start karaf no data is left there so my guess is, I need to do something with the registry when karaf closes down in order for the data to persist. However I did not find anything in the docu on how to do this.

Could anybody give me a hint?

Regards,

Konstantin

2016-05-08 03:08:42 -0700 asked a question How to get started with my own OpenFlow application

Hi,

I want to play around writing my own applications. I really want to understand how to start from scratch, what to include in order to have an application that can work on packet in messages and than do something about that.

Googling around I found a lot of tutorials many for the old sal not mdsal architecture. With the archetype described in https://wiki.opendaylight.org/view/Op...Controller:MD-SAL:StartupProject_Archetype I got as far as being able to build (but only under Linux Java 1.8 and maven 3.3 on Mac do not build) the basic project and starting Karaf I see that my test implementation is instantiated.

Now I tried including some stuff from l2-switch this compiles but than I get duplication class name errors and my service is never started. Do I need to put something in the YANG-Files or one of the POM files (dependencies?) so this works?

Essentially for starters I want a 'hello packet' message for each packet sent to the controller.

Please help :)

Konstantin

2016-03-24 09:28:28 -0700 asked a question DLUX Yang UI gets stuck in "loading/processing modules"

Hi,

I tried the Yang UI. While ODL is working with my Switches (I can see and push flows using restconf) I can see the switches in the map and in the node list. But when I click on Yang UI the browser shows me 'load modules" sometimes it progresses to processing modules, CPU is at a 100% but nothing ever happens.

Might I have installed the Yang UI wrong? I tried in stalling odl-dlux-all as well as old-dlux-core and specifically adding -ui packages.

Any help appreciated,

Konstantin

2016-02-14 03:16:03 -0700 asked a question l2-switch and tunnel ports

Hi,

I have an OVS connected to ODL using the odl-l2-switch. For directly connected ports this works as supposed to. However I have a VXLAN tunnel to a single host somewhere else and there no flows are created. Is this supposed not to work i.e. do I need manual flows so that the host behind the vxlan tunnel can reach the other hosts?

As I cut&pasted from the documentation examples and just changed IP addresses that is included.

2016-01-24 14:06:10 -0700 commented answer How to write to BGP Peers

Yes this is what is happening There are no exceptions but the message 'advertised empty attributes' behind something that looks like the description of the route puzzled me.

Hi,

is there one rib per peer or can I configure more than one peer into one rib?

2016-01-24 07:37:20 -0700 commented answer How to write to BGP Peers

OK now that I am documenting it it is not working again… I have a BGP-Peer where flowspec works find in both directions. I also learn the v4-routes but pushing one show the route in the adj-rib-in of the peer entry of the ODL host only. Any clue?

2016-01-23 07:38:24 -0700 commented answer BGP Flowspec against Juniper supported?

For keven: No I just play with Juniper and for normal BGP (v4-routes) quagga.

2016-01-23 07:37:15 -0700 commented answer BGP Flowspec against Juniper supported?

Hi I got it working now in all directions. Is there a reference guide for the language of flowspec rules anywhere? I found by comparing the settings for comm-type/subtype to get it to drop packets but I might want to do different things.

2016-01-19 10:40:21 -0700 commented answer BGP Flowspec against Juniper supported?

I am assuming that fs-route-key its what I specify in <route-key> in the route?

2016-01-18 08:57:29 -0700 commented answer BGP Flowspec against Juniper supported?

Hi, yes I can write to a real device (and verified that the traffic is actually blocked. I tested this with a VMX from Juniper. I tested with 0.3.3. Still waiting for the information on how to delete a single fs-entry. Konstantin

Hi, upgrade did the trick now I get the route from the Juniper box. Next stop ODL->Juniper

2015-12-15 09:10:31 -0700 commented question BGP Flowspec against Juniper supported?

OK I normally go by what is available on the main page, but I will try that one. Just cause I am curious (as I remember from previous releases) is there a trick to install the dlux stuff or is dlux-all ok now?

2015-12-15 09:07:39 -0700 commented answer How to set up openvswitch > 2.3 and ODL so l2-switch works?

indeed the controller is on another network on a different machine. Setting the connection mode without karat clean now gives me lot of message deserialization exceptions.

2015-12-15 08:56:32 -0700 commented question BGP Flowspec against Juniper supported?

SR3 already out or do I need to git clone?

2015-12-15 08:43:00 -0700 commented answer How to set up openvswitch > 2.3 and ODL so l2-switch works?

Hi, thanks for Your answer. Because I am curious: what does karaf clean do? Kill everything or just the state? 2nd what is different with connection-mode out-of-band? THanks, Konstanitn

2015-12-13 07:23:58 -0700 commented question BGP Flowspec against Juniper supported?

http://pastebin.com/m7Yq6cE9 is a log of what happens if I I add a flowspec rule on the juniper device and it tries to propagate it via bgp

2015-12-13 04:22:58 -0700 asked a question How to set up openvswitch > 2.3 and ODL so l2-switch works?

Hi,

I have a fresh setup with OpenVSwitch 2.3 (and a second with 2.4). If I add the controller, no switching happens. I found googling around that it is advisable to set the protocols on the bridge controlled by ODL to OpenFlow13. Still nothing happens. If I push a flow with a low priority that has the normal-action switching happens and I can do other flows to supersede this. However isn't the l2-switch app supposed to accept the new packets and then do the switching logic? Do I need to set 'controller' as default action? And no, downgrading OVS is not an option.

Regards,

Konstantin

2015-12-13 00:32:57 -0700 commented question Monitor the network traffic.

What do You mean by monitor? If You look at the flows via rest api You get some amount of data (e.g. how many packets/bytes per flow are transferred). Also Open vSwitch itself can do netflow/sflow/ipfix.

2015-12-09 12:59:39 -0700 commented answer BGP Flowspec against Juniper supported?

Can I just delete the whole <flowspec-routes> block? How can one add single routes like with ipv4?

2015-12-09 12:56:07 -0700 commented answer How to write to BGP Peers

Actually it should be both. However running a log:tail on ODL after activating this hammers out exceptions. I would like to push routes from ODL over there.
