|System Administration Guide: IP Services Oracle Solaris 11 Express 11/10|
In each exclusive-IP zone, the VRRP service svc:/network/vrrp/default is enabled automatically when any VRRP router is created in the particular zone. The VRRP service manages the VRRP router for that specific zone.
However, the support for an exclusive-IP zone is limited because of the following reasons:
VNIC cannot be created inside a non-global zone. Therefore, create the VRRP VNIC in the global-zone first, and then assign the VNIC to the non-global zone where the VRRP router resides. The VRRP router can then be created and started in the non-global zone by using the vrrpadm command.
On a single Oracle Solaris 11 Express system, it is not possible to create two VRRP routers in different zones to participate with the same virtual router. The reason is that Oracle Solaris 11 Express does not allow you to create two VNICs with the same MAC address.
The VRRP service cannot work on an IP Network Multipathing (IPMP) interface. The reason is because VRRP requires specific VRRP MAC addresses while IPMP works completely in the IP layer.
Further, the VRRP virtual IP addresses can only be statically configured and cannot be auto-configured by the two existing auto-configuration tools for IP addresses: in.ndpd for IPv6 auto-configuration and dhcpagent for DHCP configuration. Because the master and the backup VRRP routers (VNICs) share the same MAC address, in.ndpd and dhcpagent can become confused. Eventually unexpected results can occur. Therefore, IPv6 auto-configuration and DHCP configurations are not supported over VRRP VNICs. If you configure either IPv6 auto-configuration or DHCP over a VRRP VNIC, the attempt to bring up the auto-configured IP address fails, as will the auto-configuration operation.
