question about STP.

HI there, 

I'm facing some ping issue. 

 

Topology is this 

Link between SW3 and SW4 is a trunk link. it allows all vlan 

SW3 e0/2 : vlan 100 (10.10.10.2)

SW4 e0/2 : vlan 100 (10.10.10.3)

all interfaces on PC5 is vlan 100 (not a pc it is a switch)

PC e0/0 : vlan 100

 

HSRP is running on SW3,SW4 side, and SW3 is a active. 

 

Tried to ping from PC to 10.10.10.1 which is VIP between SW3 and SW4. it didn't work. 

I can't even reach 10.10.10.2 and 10.10.10.3.

 

After shutting down trunk link, can ping 10.10.10.1, 10.10.10.2, 10.10.10.3.

 

what's the problem??

please correct me 

 

Thank you !!
