Re: HSRP IP Address Is Being Reported As a Duplicate IP Address.

I have already refer to the cause of this error given in this link.It says that it happens because of some wrong ethrechannel config,duplicate frames or STP loop.we dont have etherchannel here.i suspect a STP loop.can you please help me in diagonising STP,or may be some document that could help me.

Thanks..
