# Forwarding replica

A forwarding replica offers a blend of the functionality of the P4 Proxy with the improved performance of a replica.

If you are auditing server activity, each of your forwarding replica servers must have its own `P4AUDIT` log configured.

- A forwarding replica can offload read-only commands from an edge server.
  To configure the forwarding replica for this use case, set the `ReplicatingFrom` field in the forwarding replica's server spec to the server ID of the edge server. See the Form Fields for p4 server in the P4 CLI Reference.

- Prior to 2021.2, an edge server between a forwarding replica and a commit server was not supported.

- For upgrading, see Upgrade replica servers.
