IP Network Multipathing (IPMP) in an exclusive-IP zone is configured as it is in the global zone. To use IPMP, an exclusive-IP zone requires at least two zonecfg add net resources. IPMP is configured from within the zone on these datalinks.
You can configure one or more physical interfaces into an IP multipathing group, or IPMP group. After configuring IPMP, the system automatically monitors the interfaces in the IPMP group for failure. If an interface in the group fails or is removed for maintenance, IPMP automatically migrates, or fails over, the failed interface's IP addresses. The recipient of these addresses is a functioning interface in the failed interface's IPMP group. The failover component of IPMP preserves connectivity and prevents disruption of any existing connections. Additionally, IPMP improves overall network performance by automatically spreading out network traffic across the set of interfaces in the IPMP group. This process is called load spreading.
