User Guidelines
Use of the Dual Control Plane Detection Protocol is optional. It provides a
second layer of redundancy beyond that provided by the peer link protocol.
System that operate without the DCPDP protocol enabled (and use static
LAGs) run the risk of a split brain scenario in the case of peer link failure.
Example
console(config)#vpc domain 1
console(config-vpc 1)#peer-keepalive enable
console(config-vpc 1)#peer-keepalive destination 192.168.0.2 source
192.168.0.1
console(config-vpc 1)#peer detection enable
console(config-vpc 1)#exit
