Chapter 7 Configuring vPCs
Configuring vPCs
5. (Optional) copy running-config startup-config
DETAILED STEPS
This example shows how to create a vPC domain:
switch# configure terminal
switch(config)# vpc domain 5
switch(config-vpc-domain)#
This example shows how to enter the vpc-domain command mode to configure an existing vPC domain:
switch# configure terminal
switch(config)# vpc domain 5
switch(config-vpc-domain)#
Configuring the vPC Keepalive Link and Messages
Note You must configure the vPC peer-keepalive link before the system can form the vPC peer link.
You can configure the destination IP for the peer-keepalive link that carries the keepalive messages.
Optionally, you can configure other parameters for the keepalive messages.
Note We recommend that you configure a separate Virtual Routing and Forwarding (VRF) instance and put a
Layer 3 port from each vPC peer device into that VRF for the vPC peer-keepalive link. Do not use the
peer link itself to send vPC peer-keepalive messages. For information on creating and configuring VRFs,
