Configuring DLSw Ethernet redundancy
DLSw Ethernet redundancy implements backup and load sharing, and enables multiple DLSw
routers to connect to the same Ethernet.
To prevent two or more DLSw routers connected to the same Ethernet from establishing multiple
circuits for the same SNA session, DLSw Ethernet redundancy uniformly manages all DLSw routers
connected to the same Ethernet. DLSw Ethernet redundancy selects a primary router, which will
uniformly manage the circuits. The primary router can assign circuits to implement load sharing (try
to establish the same number of circuits on each DLSw router). Any circuit established on a DLSw
router must be permitted by the primary router. The circuit assignment policy improves the network
resource usage when multiple DLSw routers are running.
