# Forwarding replica overview

A forwarding replica offers 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.
