Hi Guys,

 

I have ran in a wierd situation where my HSRP active router changed its state from ACTIVE to Speak with out any high priority box being introduced.

Can some one explain why did the Active Switch SW01 for VLAN191 went from active to speak mode while there was no change done in topology and all remains same.

Hi,Do you have tracking

Hi,

Do you have tracking enabled under HSRP configuration for those interfaces? (IIf enabled, it may show in ' Sh stand vlan xxx' but I'm not sure). One possibility is if tracking interface not available the Active router may experience this behavior.

Thx

MS
