PPPoE issue with latest rolling release


latest rolling release seems to have some pppoe issues.
After disconnecting and reconnecting the line e.g. after 24 hours by the ISP the pppoe connection is established again but the configured default route is not inserted into the routing table.

The default route is configured as follows:

 route {
     interface pppoe0 {

ip route show gives: dev pppoe0 proto kernel scope link src dev eth1 proto kernel scope link src

show interfaces pppoe pppoe0 shows:

pppoe0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1492 qdisc pfifo_fast state UNKNOWN group default qlen 3
    inet peer scope global pppoe0
       valid_lft forever preferred_lft forever
    inet6 fe80::90a6:ab53:5199:ca6a peer fe80::9ecc:83ff:fec8:a1e4/128 scope link 
       valid_lft forever preferred_lft forever

    RX:  bytes  packets  errors  dropped  overrun       mcast
         40449      799       0        0        0           0
    TX:  bytes  packets  errors  dropped  carrier  collisions
           438       10       0        0        0           0

Issue cannot be solved by disconnect interface pppoe0 and reconnect interface pppoe0 (routing still missing), router needs to be restarted to solve this issue.

After restarting everything is fine again for the next 24 hours until the line disconnection by the ISP.
ip route show

default nhid 35 dev pppoe0 proto static metric 20 dev pppoe0 proto kernel scope link src dev eth1 proto kernel scope link src 

Another issue seems to be when interface pppoe0 is disconnected:

**show interfaces pppoe pppoe0**

Hi @AWHarvard

Do you use lte wan connection? Can you provide you pppoe configuration?
