General
Due to hardware limitations, L3 routing over vPC feature isn't currently supported. This is a tracking bug to document the future implementation of the feature.
Workaround:
One of the following supported topologies can be used:
• A Separate L3 link between the vPC peers
• A dedicated L2 link between the vPC peers along with a dedicated vlan(s)
• A backup routing vlan which exists on the two peers only.
Please refer to the release notes for the feature support
