vPC - peer link and peer keepalive link down scenario

[gavin han]

in case of vPC - peer link and peer keepalive link down scenario, on secondary N7K or N5K, does L3 port get suspended as well or only ports that are member of vPC & SVIs get suspended?

Gavin,

Irrespectively of layer 2 or 3 all links will be suspended on the secondary switch.

incase of both link(PKL, Peer-Link) fail, none on the vPC or nor SVI get suspend.

Hello Gavin,

It will end up in split-brain scenario, depends how your network topology is formed. Think two switches in the network spreading the same mac address and the same bridge-id to the STP process.

Instead of hosts, you get switches running spanning-tree downstream and upstream as well, in a split-brain situation you network will create a loop.

Hope it Helps..
