First we need to create a Virtual Router and Load Balancer

Note: The Full Kilo setup can be found here – How To Install Openstack Kilo On Solaris-12 With OVS

Will use vrrp v3 (solrias tech)

Install needed packages

pkg install vrrp

Disable redirects

ipadm set-prop -p send_redirects=off ipv4

on first node

The example below users – Router address 10.10.2.215

vrrpadm create-router -T L3 -V 1 -A inet -I net0 -P 10.10.2.216 \
-a 10.10.2.215/22 -p 150 vrrp1

on second node

vrrpadm create-router -T L3 -V 1 -A inet -I net0 -P 10.10.2.217 \
-a 10.10.2.215/22 -p 100 vrrp1

On each node

vrrpadm show-router -x vrrp1

To switch, just up the priorty or disable router

vrrpadm disable-router vrrp1
vrrpadm modify-router -p 200 vrrp1
vrrpadm enable-router vrrp1

VRRP setup Source

Solaris ilb setup

Lets install Solaris iLB and enable it

ipadm set-prop -p forwarding=on ipv4
pkg install ilb
svcadm enable ilb 
svcs ilb
