vMX

We are looking at using the vMX as a BRAS to terminate PPPoE sessions via the Dynamic Profile, I have beenfollowing the steps outlines in the juniper guide guide, but it's unable to create a dynamic profile due to a "ADD from daemon pppoed because enhanced-universal-edge is disabled" error.

Configuration
dynamic-profiles {
    basic-pppoe-profile {
        interfaces {
            pp0 {
                unit "$junos-interface-unit" {
                    ppp-options {
                        chap;
                        pap;
                        authentication [ pap chap ];
                    }
                    pppoe-options {
                        underlying-interface "$junos-underlying-interface";
                        server;
                    }
                    keepalives interval 15;
                    family inet {
                        unnumbered-address lo0.0;
                    }
                }
            }
        }
    }
}

interfaces ge-0/0/0
    vlan-tagging;
        unit 3500 {
            encapsulation ppp-over-ether;
            vlan-id 3500;
            pppoe-underlying-options {
                access-concentrator server-vMX-1;
                dynamic-profile basic-pppoe-profile;
            }
        }
    }
}

Which seem to show that the configuration is working but the Dynamic
Profile is not being added due to the error Operation not permitted.
Checking the messages log I see the following

Aug 29 08:18:38  vMX-1.ak pppoed: dyn_prof_send_request: Rejecting
profile (basic-pppoe-profile - use_flow: 0) ADD from daemon pppoed

Is this a result of the evaluation license not covering this? Or something else not set correctly?

Hi Mark,

You will need to enable the subscriber management features, this is done as below:

Hi Matt 

That was the part I was overlooking, 

Thanks

Hi Matt,

Thank you for your useful information.

I'm using vMX 14.1.R4.8 for BNG simulation. PPPoE client fails to receive ip address from BNG because of missing license.

Is there anyway to solve this? Thank you very much.

This is my configuration on vMX

PPPOE-PROFILE {

pp0 {
unit "$junos-interface-unit" {
pppoe-options {

Get a trail license at https://www.juniper.net/us/en/dm/free-vmx-trial/.

The vMX trial license will allow all BNG features at  unlimited scale for 60 days. After that your scale will be capped at 10 subscribers.

Hi,

Is there any reason you are using 14.1.R4.8? My recommendation would be to use vMX release 15.1F6 for your BNG simulation.

Hi, i'm running VMX version 14.1R4.8 in UNL-Unified Net Lab, it's very easy to drag and drop router for doing lab. I'm searching how to convert an ESXi VMX 15.1F6 to use with UNL.

I have a ESXi image of 15.1F5, but i got a problem when booting vFPC. It shows up an error about not enough disk space....

I'm not familiar with Vmware EXSi, so please help me.

Thank you so much.

I aasume that you are using VMDK? You may get vMX 15.1F6 OVA files to overcome this issue.

https://www.juniper.net/support/downloads/?p=vmx#sw

or direct URL to vMX ESXi package:

https://webdownload.juniper.net/swdl/dl/secure/site/1/record/62831.html

Or evan better, you can use qcow2 file in KVM package so you don't have to convert format by using qemu-img.

https://webdownload.juniper.net/swdl/dl/secure/site/1/record/62819.html

Thanks a lot Szhong,

Could you please upload to mediafire or mega, my account do not have enough privilege to download qcow2 file

Appreciate your help.

Dear Szhong,

I have a KVM version of 15.1F5, i extracted the tar file and got alot of file, including "jinstall64-vmx-15.1F5-S1.5-domestic.img", "vFPC-20160503.img", and many file with "metadata-usb" prefix.

I tried to upload "jinstall64-vmx-15.1F5-S1.5-domestic.img" to use with UNL, but it did not work.

Please help me mate.
