For remote mirroring, the source and destination are configured on different routers. Mirror source and mirror destination parameters must be configured under the same service ID context.
For SDPs use remote-source>far-end entries. Remote source far-end details are configured in the destination node.
Figure: Remote Mirrored Service Tasks shows the mirror destination (SAR-1), configuration for mirror service 1216. This configuration specifies that the mirrored traffic coming from the mirror source (10.10.0.91) is to be directed to SAP 1/1/58 and states that the service only accepts traffic from far-end 10.10.0.92 (SAR-2) with an ingress service label of 5678. When a forwarding class is specified, then all mirrored packets transmitted to the destination SAP or SDP override the default (be) forwarding class. The slice size limits the size of the stream of packet through the router and the core network.
The following example shows the CLI output for configuration of remote mirrored service 1216. The traffic ingressing and egressing port 1/1/60 on 10.10.0.92 (SAR-2) will be mirrored to the destination SAP 1/1/58:0 on SAR-1.
