3Supported Topologies

MLAGs topologies contain several options. They can be a single layer (only one pair of MLAG peer switches) or two layers (two pair of MLAG peer switches).

Each MLAG domain can have anywhere from 1 to 8 partner switches. The peer-link between peers can have anywhere from 1 to 8 active interfaces to create the link. Given these variables, there are dozens of ways to setup an MLAG. Table 2 lists all supported topology options.
