Hello

here we go

ip addr list:
66: pppoe-wan: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1492 qdisc
pfifo_fast state UNKNOWN qlen
3                                                     
   
link/ppp                                                                                                                                                

    inet 84.57.179.177 peer 84.57.128.1/32 scope global pppoe-wan

41: tun0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc
pfifo_fast state UNKNOWN qlen
100                                                        
   
link/none                                                                                                                                               

    inet 192.168.100.129 peer 192.168.100.130/32 scope global tun0

birdc show interfaces:

pppoe-wan DOWN (index=67)
        PtP Multicast AdminUp LinkUp MTU=1492

tun0 DOWN (index=41)
        PtP Multicast AdminUp LinkUp MTU=1500
        192.168.100.129/32 (Primary, opposite 192.168.100.130, scope site)


interesting: link/ppp is interpreted as "DOWN"...
