Beginning in ExtremeXOS 15.5, each MLAG switch can support the creation of two MLAG
peers. The following topology is now supported:
Two MLAG Peer Topology
All basic MLAG functionality and traffic forwarding rules that existed
earlier apply with this topology.
Note
A port is an MLAG port only with
respect to a particular MLAG peer switch. In the above example, the “green” port on switch-2 is
an MLAG port with respect to switch-3 on ISC-2. It is not an MLAG port with respect to switch-1
on ISC-1. Similarly, on switch-2, “blue” and “orange” ports are MLAG ports with respect to
switch-1 on ISC-1. They are not MLAG ports with respect to switch-3 on ISC-2.
