Do you mean that 4500 will "see" the arp response for vlan 10 hsrp address sourced by PC "000f.202f.b8c0 "?
For example, 4500----l2 switch----hub---pc1 and pc2.
If pc1 set ip to hsrp address,and pc2 send arp request for hsrp address. Both pc1 and 4500 will response it . Destination mac-address of arp reply by pc1 would not send to 4500 except unicast flooding because CAM table on l2 switch would pointed to port connected to hub.
So how did 4500 know that there is duplicate ip address ?
This message signifies that that has been a duplicate IP address encountered on the network. As 10.1.1.253 being the HSRP IP i.e virtual IP, someone has tried putting the same IP in your network or has got the same DHCP IP. If you have DHCP server in your n/e, you have to exclude this IP from the DHCP pool for Vlan 10. You also might want to check if some user has used this address as static on the system.
Check the PC" 000f.202f.b8c0 " and you will get to the root of this as it is periodically coming up and responding to arps for the vlan 10 hsrp address:
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
