Routing

Hi All,

I've been tasked with upgrading an MX10 running v11.7 to an MX204 running v21.1 to act as a BNG. I used the existing config from the mx10 on the mx204 and it seems to take it with no errors. Long story short it uses stacked vlans, dynamic profiles and radius to deal with PPPoE subscibers all with licensing that juniper confirmed.

When I put the MX204 in live environment nothing works. I think i have narrowed it down to the interface that does the auto-configuration for the stacked vlans and triggering the dynamic profile because no demux interface is created.

This is the part i think isn't working  and i can confirm i see the PADi request on the stacked vlan interface. Am i correct that the demux interface should be the next step and this would create even if the license was wrong or radius wasnt working?

This is a snippet of my config but can post more if required as i'm a little unfamiliar with the order junos processes everything regards to PPPoE, dynamic-profiles and the dreaded licensing.

set interfaces xe-0/1/2 description "PPPOE Subscriber Management"
set interfaces xe-0/1/2 stacked-vlan-tagging
set interfaces xe-0/1/2 auto-configure stacked-vlan-ranges dynamic-profile svlan-profile accept pppoe
set interfaces xe-0/1/2 auto-configure stacked-vlan-ranges dynamic-profile svlan-profile ranges 1-4094,1-4094

set dynamic-profiles svlan-profile interfaces demux0 unit "$junos-interface-unit" vlan-tags outer "$junos-stacked-vlan-id"
set dynamic-profiles svlan-profile interfaces demux0 unit "$junos-interface-unit" vlan-tags inner "$junos-vlan-id"
set dynamic-profiles svlan-profile interfaces demux0 unit "$junos-interface-unit" demux-options underlying-interface "$junos-interface-ifd-name"
set dynamic-profiles svlan-profile interfaces demux0 unit "$junos-interface-unit" family pppoe dynamic-profile PPPoE-Profile

Any help appreciated !
