Hello Wei,

The VXLAN with EPVN is poorly documented, then I need all tthe guidance as possible from the community.


There is no silver bullet here as each EVPN+VXLAN setup will differ from the other :-)

Wido, please kindly allow me to use some of your multiple answers to several members of the community as reference. As there is really not much info.

  * Wei what you suggesting I did try that, already, I did try several
    options so far. The cloudstack-Agent keeps restarting itself, I copy
    the logs in the e-mail.
  *

  * Saw countless videos, and read the manual, the Manual only states in
    summary "VXLAN with EVPN is complex", there is nothing else.
  *

  * Manual states use and modify "modifyvxlan-evpn.sh" which does not
    exists. Using the one form github. modifyvxlan.sh
  *


Yes, the Github one is good. It will be in packages from 4.21

   *  The manual indicates: showing a picture of Management,public and
    storage on vlans. and indicates - The only thing you have to do is
    configure the physical Network to use VXLAN as the isolation method
    for Guest Network - We do not have VLANS at all.
  *


Don't worry about different networks, VXLAN creates it's own bridges on the fly.

  * Per one of the e-mails iIread long time ago from Wido to another
    member of the community: we do left the UI settings by default. That
    didn't work. And we start experimenting, and none seems to be working.


It has been a long time since I've set it up. But you should just have cloudbr0 and cloudbr1, nothing else.



Per Wido, we only need cloudbr1, with no VLANs.

I only need to know on the cludstack UI, What do we point to the Cloudbr1 My understanding is This is going to be used for Migrations ad that.

4.20.0 does not allow me to add Management alone, nor the Guest Alone, when creating the first zone.

I need Public and Management at least. Right? Or please indicate which ones. I try to add only the Guest one, it also fails


Additionally, seems like the Cloudstack is not smart enough to see what VNI VXLANs are already configured, then I have to provide a vni range for the Guest. Although the modifyvxlan.sh script should take care of it - that is based on reading the script code.


So far we do have VXLAN-EVPN reachability and working.

I think we are almost there:

  * I try adding Guest Only during the zone creation, we do have
    management, public and storage on VXLANS, all are reacheable by
    routing, and the cloudstack-agent server reach them and have
    cloudbr1 created.
      o Should I have only Managment and Guest on the cloudbr1?
  * Need help Guidance with The cloudstack-agent keeps Bouncing comes up
    and immediately down, and even reinstalled removing all files. Still
    the same.
  * Any example of the initial agent.properties: Or do not touch the
    agent.properties


Only set the network devices as you've done below. The guid should match what the hypervisor thinks the UUID of this Agent is. Again, long time ago since I've set this up for the first time.

Wido


My agent.properties I have modified specifically 3 parameters:

host=<MAMGT-IP1>,<MGMT-IP2>

guest.cpu.mode=host-model

private.network.device=cloudbr1


Thank you for your guidance.

Thank you

Tata Y.

I think you do not need to change agent.properties
Instead, you need to set the network traffic label of each traffic type, for example cloudbr1.

By default, management traffic uses cloudbr0, public and guest traffic use cloudbr1, which might not be what you use.

    Hello Apache Cloudstack users,


    After attempted some options, I am recurring to what should work.
    As there is no info in the documentation about this deployment.

    I did replaced the agent server with private.network.device=cloudbr1

    I have my VXLAN 1 on Cloudbr1 that reaches management and SS, We
    only have cloudbr1 created, No other bridge, and everything is BGP.


    Then at the UI creating the ZONE I got errors:

    We have had tryed the following Options:

    *Option 1: *No tags
    I put only [Physical Network 1] [VXLAN] Management, throws a popup
    error " All required traffic types should be added and with
    multiple physical networks each traffic type should have a label"

    *Option 2:* No Tags, Throws and Error " All required traffic types
    should be added and with multiple physical networks each traffic
    type should have a label"
    I put :
    [Physical Network 1] [VXLAN] Management
    [Physical Network 2] [VXLAN] Public
    [Physical Network 3] [VXLAN] Guest
    [Physical Network 4] [VXLAN] Storage


    *Option 3: *
    I put :
    [Physical Network 1] [VXLAN] Management, Public, Guest, it goes to
    the next window - which is Great
    The the system throws exceptions like:
    *Something went wrong; please correct the following:*
    *Unable to add the host: Cannot find the server resources at
    http://<KVM-IP>*

    sed -i 's/INFO/DEBUG/g' /etc/cloudstack/agent/log4j-cloud.xml
