Abstract
Methods, systems, and apparatus for selective MAC address learning are disclosed. In one aspect, multiple different packets are received by a telecommunications device. The multiple different packets include different source MAC addresses. For each of the multiple different packets, a distribution type is determined. The distribution type is one of a one-to-one distribution type or a one-to-many distribution type. Based on the determined distribution type of the particular packet, a forwarding table of the telecommunications device is selectively updated. When the particular packet has the one-to-many distribution type, a source MAC address that is included in the particular packet is not stored in the forwarding table. When the particular packet has the one-to-one distribution type, the source MAC address that is included in the particular packet is stored in the forwarding table.
