Constant `Link: DOWN event` in point to point logs

[40hzshadow]

First of all this is my first time using Opensense. I'm sure I'm not setup correctly, that said I do have internet connection and a IP from my ISP.

I have fiber internet in the Pacific NW with century link. They use PPPOE and have me on vlan tag 201.

I'm using this little bee link micro pc as my router.

In my config

* Interfaces -> WAN -> PPPOE ->  Modem Port:  igc1,vlan01  (same as from my point to point)
* Interfaces -> Interfaces -> Assignments -> [WAN] -> pppoe1
* Interfaces -> Other Types -> VLAN (vlan01, Parent: igc1, tag: 201, PCP: Best Effort (0, default))
* Interfaces -> Point-to-Point ->  Devices (pppoe1, Interface: ( igc1,vlan01 )
     Link Type: PPPOE with all my ISP creds


On reboot I get a wan gateway and a public IP without issue and my internet seems to be working fine.
Hardwire I get full ~950mb up and down.

Aside from that I see these logs filling up by the second in my Point to point.

```

2024-08-20T13:01:44-07:00   3   Informational   ppp   11708   [wan_link0] Link: DOWN event
```

I have tried all the other combinations for linking the point to point interfaces but currently this is the only way I get an IP
Though I assume I'm still doing this wrong. What am I missing?

Thanks.

I only see one instance of the link down. How frequent WRT "constant" is this?

it repeats this log every few seconds. Currently in a single day it says its on `attempt 6281`
I wipe the logs once a day.

How does this stay connected then?

Good question, I assume its logs for something other than my live connection. Maybe the way I have the topology is causing this as a result of two connection paths? IDK, thats why I'm here. 

Again I get full gig ~950mbps on speed test hardwired.

Do you maybe have issues with IPv4 but use IPv6 directly over the WAN link without PPPoE?

PS:

> Modem Port:  igc1,vlan01  (same as from my point to point)

You run MLPPP over igc1 and the VLAN on top of igc1??? I think you only need one. Maybe that's why you get a failure message for the other...

I have IPV6 disabled and only use IPV4 in PPPOE in both the wan settings and the point 2 point.

[franco]

Yes I think it's your MLPPP config that you definitely do not want.

So this is my thought too. but if I only set my Point to point as vlan then I don't get my IP or gateway.  So far this is the only way I get the connection to stay up, but from what I read this is likely the issue
