Who owns the ARP Table and FDB in the context of a linux network namespace?
I'm trying to understand linux overlay networks. I understand a bridge serves the combined function of an L2 Switch and L3 Router. It uses an ARP table for IP -> MAC mapping, and an FDB for MAC -> iface mapping. But where exactly do these tables recide and who 'owns/manages' them?
For instance, suppose you create a linux bridge in a network namespace and attach 2 veth interfaces to it.
- Does each veth interface maintain its own ARP & FDB table?
- Or does the bridge maintain one table for all interfaces?
- Or is it the namespace that manages the table?
