I have configured HSRP in VLAN 1 on both core switches. Core 1 is active and core 2 is in standby mode. I can see standby,active IP and VIP on both core switches.
But from Core 2 (standby) i could not ping VIP,active Ip address.
1.Connection between two core switch is etherchannel.
2.Etherchannal is up and able ping other VLAN's VIP from core2.
3.Did shut and unshut on core2 VLAN # 1 interface , but still not rechable.
4.In core 2, i can learn ARP entry of VIP and active IP
5.From core 1 i can't ping standby IP of VLAN 1. other VLAN's standby IP reachable.
6.Native VLAN is 100. Etherchannel allowed vlan 1 on both side.
7.Switch model is Cisco 3750. IOS - 12.2(55).SE5
Any guess what could be the issue.
