Where eth0 goes down

That is wan

https://community.ubnt.com/t5/EdgeRouter/quot-routing-protocols-may-malfunction-quot/td-p/467015

From what i asked, that is a warning, not an error

I found that one too, last post is a "fuck it"

yeah

Will not cause eth0 to drop

basically if your config is correct, then it seems like it doesnt matter

but your config might be incorrect

what router do you have?

It is a dhcp mode to pick up ip from the modem

@Grenade123 unifi usg

have you tried restarting it by chance?

Yes

Now get this, isp modem showed a restart on the same time as my eth0 goes down

tried resetting the dhcp?

>but random restart is not indicative of hardware failure

@Grenade123 you mean the modem dhcp server

It gotnpower cycled

Wan is having issie

Not lan

Different

Dhcp is to correct lan issues

But wan is handled by modem

Otherwise you will have modem acting as router and router being router, you will get 2 routers

It does look like a DHCP client issue involving eth0.

Not really

Their modem gives a private ip on startup, then gives a public ip on link establish with internet

"?Looks like the dhcp client under eth0 made zebra thinking the broadcast address wasn't right. If WAN/Internet access is fine then there isn't much to worry about. You can try renew dhcp for eth0 see if the message would occur again, also you can check "show interface ethernet eth0", "show ip route", and "show ip route forward" outputs see if anything doesn't look right"

It is still routing fine since internet worked for days on end

that was from the post i linked earlier

but on a different note, have you tried power cycling the modem?

and any other routers on the network

Yes

The error was after the power cycle, about 1 hr after

Where on earth is it getting '255.255.255.255/24 != 82.xx.xxx.xxx'? The IP settings on eth0 must be jacked up.

Dhcp from isp is stupid

It goes from private to public

I read that as ICP

I'm like

the fuck do juggalos have to do with this

DHCP is standard for ISP's.

Not when they go from private ip to public ip

That doesn't matter for the DHCP configuration of the public interface on the home router.

NAT lies above the physical interface configuration.

Nat is layer 3, issue is at layer 2

Or at layer 1

I'd say the issue is at the DHCP server on the ISP side.

So how does a potential misconfig at L3 affect L2

Most likely

But isp playing me by saying they dont see an issue

The L3 misconfig is in the DHCP configuration being sent by the ISP's DHCP server.

But ip i recognize is fine, so even if the dhcp is misconfig, i got the right routing

This that misconfig is equivalent to spam log, since it does not affect routing

At least for me

I already asked this with the devs that made the router, i showed my routing, they concluded it is spam log sonce routing in routing table is fine

255.255.255.255/24 sounds like garbage sent by the DHCP server.

Ok, well, if the eth0 config actually shows valid address and network and broadcast for what I assume is an 82.x.x.x/24 address then it's the log message that's garbage.

I'm not esp knowledgeable with routing but I was under the impression broadcasting is handled by the router @ the local subnet. How would 255.255.255.255 be a misconfiguration if that address is supposed to be resolved to that subnets broadcast ip? Or do I just not know what I am talking about here

I'm probably wrong here, just curious and I studied a little bit of routing once upon a time

255.255.255.255 wouldn't occur anywhere in the IP config for an interface with a /24 adddress.

It would only occur in the routing table for a routing entry pointing to a specific host.

Are there any lines in the routing table with a mask of 255.255.255.255?

And with that my knowledge is exhausted. I was under the impression that addresses like 127.0.0.1 and 255.255.255.255 were treated as special addresses that were valid regardless of the mask

It depends

All i know is it doesnt matter when routing still gets the right ip

Probably true. Could even be that it is configured right and some error in the logic being used to validate the broadcast address is reporting some value wrong causing the log to show up incorrectly

either way, glad I don't work in routing <:moon2S:289036583209009152>

You know who I want to see in the movies but I have zero faith of seeing a good adaptaation of?

Darkseid

Wheras adapting Thanos from raving lunatic to well-intentioned madman was a good idea

Darkseid is meant to be EVIL.

He is the most deadpan cartoonishly over the top black-hearted bad guy in DC

He deserves real respect to be done right

Anyone here really into computers?

I left when the chat died aghh

I'd be talking more but doing a mixture of getting shit done and not getting shit done. It's a really intricate process

@R9b1t how do you mean "really into computers"?

being into them is, in some sense, a major part of my job.

Well I convinced my father you can download more ram without windows operating systems.

Moral of the story is I need a moderate computer for video games that I plan to use mostly for office work

But I’m not sure about brand or what I can run
