VRF Support

You can configure catena service in the default VRF or in non-default VRFs.
For the catena service to successfully redirect traffic, all the ingress interfaces and device-group nodes must
belong to the same VRF. You must ensure that all ingress interfaces and node members within the associated
device group are reachable in the configured VRF.

Catena Configuration Process

You can configure Cisco Nexus devices such that packets can be redirected through multiple devices using
Catena.
To configure catena:
1 Enable catena.
2 Create a port group.
