Subject: [VRRP] Question on Election Algorithm

Hello,
 
I'll appreciate an opinion on the following issue:

To the same LAN 2 routers (R) are connected :
R1 with ifIndex 2.
R2 with ifIndex 2.
 
R1 has Primary IP address: 10.1.1.99
R2 has Primary IP address: 10.1.1.101
 
R1 & R2 has same priority ( default priority = 100 ).
 
We configure one VR12:
VR12 = {Non-Owner = R1, Non-Owner = R2, AssoIpAddr =  10.1.1.100,vmac = Vmac1}
 
We start VRRP on router R1. Since it receive no advertisements it become master.
Then we start VRRP on R2. Since it is NON- Owner it transition to backup state. It receive advertisement from R1.
According to the RFC, R2 will not become master ( although it has a higher Primary IP address than R1 and should have been the master ) because it is in backup state and doesn't compare Primary IP address( only in Master state Primary IP address are being compared in case of equal priority).

Am I correct ? 
 
Regards,
Lior
