Can IP Multipathing (IPMP) be used with zones?

Yes. Exclusive-IP zones can use IPMP. IPMP is configured the same way in an exclusive-IP zone as it is on a system not using zones. For shared-IP zones, IPMP can be configured in the global zone. Failover of a network link (e.g. hme0) that is protected by IPMP will bring the associated logical interfaces (e.g. hme0:3) for the zones over to the secondary link (e.g. bge0). For more information, see the section “Using IP Network Multipathing on a Solaris System With Zones Installed” in System Administration Guide: Solaris Containers-Resource Management and Solaris Zones. Take extra care with IPMP and the defrouter setting. See this blog entry.
