I have two CSSs 11150 and have configured them as following:
ip address 188.8.131.52 255.255.255.0 ip virtual-router 1 priority 105 preempt ip redundant-vip 1 184.108.40.206 ip critical-service 1 up_down_stream no redirects
ip address 220.127.116.11 255.255.255.0 ip virtual-router 1 priority 101 preempt
ip redundant-vip 1 18.104.22.168 ip critical-service 1 up_down_stream no redirects
Here is my connection:
CSS-1 <=> Switch <=> CSS-2
They were working fine before but CSS-2 suddenly change to master few days ago. I have already checked the connection between these two CSSs and it seems ok, so I tried to capture the packet trace both for the ports connected to CSS-1 and CSS-2 from the switch. And finally I found that I can see the vrrp adv. message which send from CSS-2 at the port which is monitoring CSS-1, but there is no vrrp adv. message send from CSS-1. I am not sure the problem is related to the acl as it has configured to permit any any:
clause 254 permit any any destination any
Could anyone can help me in this case? Is the problem related to the keyword "preempt" in CSS-2? Is it a software bugs which hasn't listed in cisco bug list (SW Version: 6.10)?
