I seek your help for clarifying the HSRP concept. I am unable to test this in the Lab. So Kindly share your experience.
Please find the attached Diagram.
I have 2 Cisco 3560 Switch connected and a Trunk link is configured between them allowing all the VLANs.Also HSRP is configured with VIP as 192.168.1.100. A server is connected with Teaming / Multipath configured in its NIC.
SWITCH 1 is ACTIVE & SWITCH 2 is STANDBY.
By Chance if the trunk link between the switches goes down as far as I know both the switches will become ACTIVE.
In the above scenario, how the traffic flow path is going to be. Since the VIP MAC will be given by both the switch, which path the Server NIC will choose.
Hope the diagram and explanation is easy to understand.
Looking for your exper comments
Thanks for you response. Your comments are very useful.
So, you say that in this scenario it will have unpredictable behaviour and packet loss is expected.
So, shall I say that the solution to avoid this issue is "connecting another cable between the Switches and configure Etherchannel" ??
Anyother best practise solution is also highly appreciated
Best practice is always to run more than one physical link between 2 switches doing HSRP, so yes you should definitely look to use etherchannel for link redudancy.
