IPMP Configuration (Probe based)

Lets set up using 2 physical interface with 2 virtual IPs.

Physical interfaces ce0, ce3
Logical interfaces ce0:1, ce0:1

Lets put the IPs into the /etc/hosts.

172.20.1.10 mynic-ce0
172.20.1.11 mynic-ce3

172.20.1.12 application1-service
172.20.1.13 application2-service

Verify local-mac-address? is set to true.
# eeprom local-mac-address?
local-mac-address?=true

Impt! - setting local-mac-address to true will not take effect until next reboot*

If this host will not be forwarding packets set the following.
# touch /etc/notrouter

Manually plumb the interfaces (ignore if you plumb them already)

# ifconfig ce0 plumb mynic-ce0 netmask + broadcast + -failover deprecated up
# ifconfig ce3 plumb mynic-ce3 netmask + broadcast + -failover deprecated up
# ifconfig ce0 addif application1-service + broadcast + failover up
# ifconfig ce3 addif application2-service netmask + broadcast + failover up

Check using /usr/sbin/ifconfig -a.

Lets make the configuration persistant across reboots.

--- /etc/hostname.ce0 ---
mynic-ce0 netmask + broadcast + group production deprecated -failover up \
addif application1-service netmask + broadcast + failover up \
addif application2-service netmask + broadcast + failover up
--- EOF ---

--- /etc/hostname.ce3 ---
mynic-ce3 netmask + broadcast + group production deprecated -failover up
--- EOF ---

8) Now lets test the failover by pulling the ce0 cable. watch /var/adm/messages for the errors.

9) you can now get the applications and users to use the IP application1-service and application2-service

Impt!! network traffic on application1-service can be incoming and outgoing BUT network traffic on application2-service can only be incoming. I have tried to play around with the deprecated tag but only managed to get network traffic going out from application1-service. Well, if you have any advise on this, do let me know!! :)
