Configuring Virtual Port Channels
• Ensure that you have enabled the vPC feature.
• Ensure that you are in the correct VDC (or use the switchto vdc command).
• Peer-gateway and peer-routing on Layer 3 over vPC are enabled on both the peers.
• Ensure that the peer link is up
Procedure
Command or Action
Step 1 switch# configure terminal
Step 2 switch(config)#vpc domain domain-id
Step 3 switch(config-vpc-domain)# peer-gateway
Step 4 switch(config-vpc-domain)# layer3 peer-router
Step 5 switch(config-vpc-domain)#exit
Step 6 (Optional) switch# show vpc brief
Step 7 (Optional) switch# copy running-config startup-config
Example
The following example shows how to configure a Layer 3 over vPC:
switch# configure terminal
switch(config)# vpc domain 2
switch(config-vpc-domain)# peer-gateway
switch(config-vpc-domain)# layer3 peer-router
switch(config-vpc-domain)# exit
switch(config)#
The following example shows how to verify if the Layer 3 over vPC is configured:
Purpose
Enters global configuration mode.
Creates a vPC domain on the device and enters the
vpc-domain configuration mode for configuration purposes.
There is no default; the range is from 1 to 1000.
Enables Layer 3 forwarding for packets destined to the
peer's gateway MAC address.
Enables the Layer 3 device to form peering adjacency with
both peers.
Note
Exits vpc-domain configuration mode.
Displays brief information about each vPC domain.
Note
Copies the running configuration to the startup
configuration.
