Hi there
I need to shift the interface used for the VPC peer between 2 of my Nexus Switches to a different interface. I plan to bind a different IP address on the new VPC peer interface on both switches before the change and then during the outage window, just change the "peer-keepalive destination x.x.x.x source x.x.x.x vrf default" line of config.
By making this change, what is the expected result in terms of an outage? Will the VPC relationship be broken momentarily and a spanning tree calculation occur which normally results in a outage which could last around 2 minutes, or is it possible to achieve this without any outage?
Thanks

Hello Maxwell,
Changing the keepalive address will not have any impact rather then a log that will say that the keep-alive failed while the 2 devices are not able to ping. This is valid as long as the peer-link is up and stable. Peer-link has an higher weight on detecting if the other switch is live, so as long the peer-link is up nothing will change.
Make sure you use an L3 interface (no-switchport) on both sides to avoid any problems, or you could always use the mngt0 interface if your topology/policies allow it.
