what happens when mac address dynamic learning is disabled

Without any special treatment, loops would prevent network from functioning normally, as they would lead to avalanche-like packet multiplication. Network loops may emerge (intentionally or not) in complex topologies. As bridges are transparent, they do not appear in traceroute list, and no utility can make a distinction between a host working in one LAN and a host working in another LAN if these LANs are bridged (depending on the way the LANs are interconnected, latency and data rate between hosts may vary).

The bridge feature allows the interconnection of hosts connected to separate LANs (using EoIP, geographically distributed networks can be bridged as well if any kind of IP network interconnection exists between them) as if they were attached to a single LAN. 11.3 VLAN Example #3 (InterVLAN Routing by Bridge)Įthernet-like networks (Ethernet, Ethernet over IP, IEEE 802.11 in ap-bridge or bridge mode, WDS, VLAN) can be connected together using MAC bridges.11.2 VLAN Example #2 (Trunk and Hybrid Ports).11.1 VLAN Example #1 (Trunk and Access Ports).
