VRRP question

$

0

I'm trying to get VRRP on dot1q sub-interfaces working.  I'm seeing some strange behaviour with both sides being MASTER

R1 ->2960 stack port 1/0/1
R2 ->2960 stack port 2/0/1

 

sho run int g1/0/1

interface GigabitEthernet1/0/1

 description RTR1Ge0/0

 switchport mode trunk

end

 

sho run int g2/0/1

interface GigabitEthernet2/0/1

 description RTR2Ge0/0

 switchport mode trunk

end

 

sho int trunk

Port        Mode             Encapsulation  Status        Native vlan

Gi1/0/1     on               802.1q         trunking      1

Port        Vlans allowed on trunk
Gi1/0/1     1-4094
Gi2/0/1     1-4094
Port        Vlans in spanning tree forwarding state and not pruned
Gi1/0/1     1-3,5,38-39,43-45,100,246-247
Gi2/0/1     1-3,5,38-39,43-45,100,246-247

Shut, no shut int g0/0.2 and I get the following on R2
Apr 22 14:52:09.461 UTC: %VRRP-6-STATECHANGE: Gi0/0.2 Grp 2 state Master -> Init 
Apr 22 14:52:14.853 UTC: %VRRP-6-STATECHANGE: Gi0/0.2 Grp 2 state Init -> Backup
Apr 22 14:52:18.465 UTC: %VRRP-6-STATECHANGE: Gi0/0.2 Grp 2 state Backup -> Master
======================
The wierd thing is other sub interfaces show up as master and backup correctly while some do not.  I'm baffled.  Any ideas?
