Add interface option for metalLb layer2 avertisement.

[tux-box]

Is your feature request related to a problem?

Metal Load blancer avertises layer 2 anouncment across all interfaces.

Describe the solution you'd like

Give us a way to configure the interface for the l2avertisement and lockdown metallb to a specfic network interface/port https://metallb.universe.tf/configuration/_advanced_l2_configuration/

Describe alternatives you've considered

I've considered editign the config my self, but I don't belive that to be wise. I've considered not using metalLB, but I prefer to have my apps get an IP. I've not considered an alternative as I'm not sure there is one.

Thank you for your consideration.

The assumption and advice you got on discord is wrong. MetalLB only advertises accross interfaces with the correct (same) subnet as the IP/subnet you're trying to use.

If you got trouble here, you are likely having multiple interfaces on the same subnet, which is, generally speaking, ill adviced anyway.

While i'm okey with this request, this is the second time it got submitted and the second time the staff was sharing bad information. The correct solution to the problem is not having interfaces with overlapping subnetmasks, metallb does not announce on non-matching interfaces.

Thank you very much.

I have a dedicated/24 net assigned to each interface. So I'm not sure where to go from here, I've removed metalLB for now.

Hi. Same need. 2 interfaces with different networks. My switch complains than IP's of network1 appears on the network2 interface (and vice versa). Regards

Don’t +1, doesn’t help and people who’ve replied get unnecessary notifications/replies, thanks
