syslog vrrp VIP list mismatch


the vrrp is operational, bu as the log shown below, I would like to know what caused the MISMATCH? thanks.

From what I could find this message is caused by an L2 loop on vlans within the network. Is there any chance you could run ELRP to check for a L2 loop somewhere? If you cannot find anything could you provide the vlan configurations as well and also show the output of "show edp port all" for each of the switches?

Bill
thank you, bill.

I agree it may cause by a L2 loop, a elrp one-shot command was ran on sw1 to try to find the loop, but no loop detected, and sw2 configured elrp on each vlan, also no loop detected. please advise. Below link is output of show edp port all, show vrrp, show configuration vrrp, configure elrp one-shot...

Sounds good... let me digest the configurations and see if I can identify anything. What version of code and second have you already opened a case on this, if so let me know the # - if not no worries.
case # 01114102, show tech output file already enclosed to the case.

please enable mac movement for that vlan and check if you can see any mac move logs.
same problem i am getting on my core..
and found nothing suspicious by elrp

Most of the times these VRRP warnings are caused by a L2 loop, ELRP would send Multicast packets to detect the Loop, in case some devices like IP phones does not flood the multicast packets ELRP would not detect a loop even though there is a loop, so tracking the cables would help to find the loop.

What is happening here (and I am basing my conclusion on the logs) is a loop across VLANs.

Let's examine this log message:
04/12/2015 12:56:52.04 MSM-A: Advert for VR on vlan V2303D vrid 1 ignored: couldn't find VIP 10.132.0.254 in VR's list

What this log message is saying: for the VRRP instance in VLAN V2303D, the IP 10.132.0.254 is outside its subnet. It looks like VRRP packets with VIP of 10.132.0.254 are making it to VLAN V2303D some way. To me it looks like V2300D is somehow looped into VLAN V2303D.

Let me know if this helps.
