Defining node-selectors.match-labels for the peers in ECFE configuration enables traffic separation by node selectors. This feature configures ECFE speakers to connect with only those peers from the worker nodes that match the match-labels of the node-selectors of the peer. In case a peer does not have node-selectors configured, all the ECFE speakers in the cluster will establish connections with this peer.In the following example ECFE configuration, only the speaker on worker node with label "system-pool" is used if user specifies the "system-pool" for the node-selectors.
