[FUG-BR] CARP - Alta disponibilidade de ips /30

Sexta Abril 13 09:32:31 BRT 2012

ok..

eu nao estava entendendo como fazer as configurações no rc.conf
ai ficou assim

MASTER
ifconfig_em1="up"

/usr/local/etc/freevrrpd.conf

[VRID]
serverid = 1
interface = em1
priority = 101
addr = 192.168.50.49/30
password = vrid1

SLAVE
ifconfig_em1="up"

/usr/local/etc/freevrrpd.conf

[VRID]
serverid = 1
interface = em1
priority = 100
addr = 192.168.50.49/30
password = vrid1

/var/log/messages

Apr 12 18:09:45 master freevrrpd[2024]: launching daemon in background mode
Apr 12 18:09:45 master freevrrpd[2025]: initializing threads and all VRID
Apr 12 18:09:45 master freevrrpd[2025]: reading configuration file
/usr/local/etc/freevrrpd.conf
Apr 12 18:09:45 master freevrrpd[2025]: no IP address is configured on the
real interface em1
Apr 12 18:09:45 master freevrrpd[2025]: cannot join multicast vrrp group
without a real ip adress on em1
Apr 12 18:09:45 master freevrrpd[2025]: choose an IP address that is not
used on any VRIDs and restart
Apr 12 18:09:45 master freevrrpd[2025]: you can set a private address for
announcing VRRP packets (eg: 192.168.0.1/24)
Apr 12 18:09:45 master freevrrpd[2025]: exiting...
