I have two Cisco 7600 with sup720. HSRP is configured on interface VLAN, and all linecards have DFC. Because of HSRP unicast flooding is experienced in my network. I tried with increasing mac-address-table aging to 4 hours, but it didin't help. I also tried reducing arp timeout to 5 min which also didn't give any resulsts. Does anyone have any suggestion how to fix this and also why the above mentioned actions didn't help.
Thanks in advance
