Hi All,
I have a small query on VPC mac address table.
Lets say I have below topology.
N7K1 N7K2
| |
| |
N2K1 N2K2
| |
| |
| |
| |
END Device
I have below queries regarding VPC peers MAC table in normal scenario (both peers up)
> Am I expected to see end device MAC address on both N7K peers with respective FEX edge port?
> Can I expect to see any of VPC peer MAC table for this MAC pointing to VPC peer link.

Hi,
In this design, you see the mac address of an end device on the primary switch (say N7k1 is the primary) and on the backup switch, you will see the same mac address through the vPC peer-link.

Hi Reza,
Thanks for your answer. So in this case if I ping from secondary N7K box to end host, it wont be reachable. Right? as peerlink will not pass data trqaffic if the member port is up on local box.
Please advise, as I do not have lab to test.

Hi Godwin,
So, you need to deploy HSRP or VRRP per vlan with one of the boxes being the primary (active) HSRP or VRRP device and the other one work as stand-by. In this case you, you should be able to reach the end host from both switches.

Hi Reza ,
Can you brief why will it start pinging after deploying HSRP ? Why was it not pinging before ?
Thanks!
