Answer
Bridge networks and veth interfaces scale ARP/MAC tables, causing lookup latency and overhead.
Quick Answer
In overlay networks, each container advertises its MAC and IP via VXLAN. With many containers, the ARP table grows — switches and hosts track more entries. At extreme scale (thousands of containers on one overlay), ARP flooding and table overflow become real issues. Modern solutions use BGP or eBPF-based networking instead.
