Introducing IPMP (Overview)

IP network multipathing (IPMP) provides physical interface failure detection and transparent network access failover for a system with multiple interfaces on the same IP link. IPMP also provides load spreading of packets for systems with multiple interfaces.

This chapter contains the following information:

• Why You Should Use IPMP

• Basic Requirements of IPMP

• IPMP Addressing

• Solaris IPMP Components

• IPMP Interface Configurations

• IPMP Failure Detection and Recovery Features

• IPMP and Dynamic Reconfiguration

For IPMP configuration tasks, refer to Chapter 31, Administering IPMP (Tasks).
