Greetings,

I have strange problem with keepalived 1.2.7 on CentOS 6.5 x86.
Can someone advice me working solution to deal with problem?

Description:
Keepalived with EQUAL state enabled won't recognize second master and 
initialize re-election. Instead it was keeping VIP binded on both nodes.

Reproducible: 100%

Steps to Reproduce:
1. Disable iptables;
2. Enable STP on Cisco-switch;
3. Unplug cables from switch;
4. Plug cables to switch and run keepalived with following config:

5. Wait for about 40 second to allow STP to complete;
6. Run tcpdump and you will get following results: 
http://pastebin.com/0MMky6rq

Actual results:
Multicast VRRP traffic is seen by both of nodes but they continue to 
keep VIP.

Expected results:
One of node must unbind VIP.
