Replication mutli-master via DNS record ?

Hi all,

I have 3 masters and 3 slaves. Two DNS records : - Masters are recorded under master.toto.fr - Slave are recorded under slave.toto.fr

Two type of replication :

a) Slave to master Slaves replicate from one of 3 master with this configuration :

syncrepl rid=100 provider=ldap://master.toto.fr/ type=refreshAndPersist interval=00:00:30:00 [...]

b) Master to multi-master Mirrormode is set to TRUE. Can I use only one "syncrepl" with the DNS record ldap://master.toto.fr Or should I set one "syncrepl" for each master ?

I mean , in my master1 conf file can I use this :

syncrepl rid=1 provider=ldap://master.toto.fr/ type=refreshAndPersist interval=00:00:30:00 [...]

or

syncrepl rid=12 provider=ldap://IP_master2.toto.fr/ type=refreshAndPersist interval=00:00:30:00 [...] syncrepl rid=13 provider=ldap://IP_master3.toto.fr/ type=refreshAndPersist interval=00:00:30:00 [...]

Thanks guys.
