Hi ,
Network structure
Switch A --- Customer firewall 1
|
Switch B --- Customer firewall2
May be some one can help me.
There was a nagious alert yesterday and on investigation I found the 'Duplicate address x.x.x.x(VIP) on Vlanxxx, sourced by 0006.b19c.c5d9' error
It a HA feed from our switches which is going to customer firewalls.
On further investigation I have found on our switch A the ARP table is not learning the VIP address from this mac-address where as on switch B is learning the VIP address through mac 0006.b10c.c8d9 which is customer sonic firewall which is not a normal behaviour.
Our switches are Cisco 3560 switch.
Please if you could let me know what causing this.
