Hello,
I created mesh topology to learn/exercise features for exam and among others there is HSRP.
HSRP looks to work to fine and do the job as intended. My concern is about frames flooding out of all interfaces. Switch should learn mac address of HSRP virtual interface after few frames but not in my case. After countinous ping it's flooding all the time and I was concern about bandwidth usage. It should work like this or I just missconfigured something? Maybe PT bug?
Just checked DSW1 and DSW2 HSRP virtual mac address and on both it is the same. It should be, right? I wanted also to divide logic topology with PVST+ and it looks to work fine to. Vlan2 root switch is DSW1 and for vlan1 and vlan3 there is DSW2.
