Applying Layer 2 Port Mirroring to Traffic Forwarded or Flooded to a VPLS Routing Instance

 

You can apply a Layer 2 port-mirroring firewall filter to traffic being forwarded or flooded to a VPLS routing instance. Only packets of the specified family type and forwarded or flooded to that VPLS routing instance are mirrored.

Before you begin, complete the following task:

  • Define a Layer 2 port-mirroring firewall filter to be applied to the traffic being forwarded to a VPLS routing instance or flooded to a bridge domain. For details, see Defining a Layer 2 Port-Mirroring Firewall Filter.

    Note

    This configuration task shows two Layer_2 port-mirroring firewall filters: one filter applied to the VPLS routing instance forwarding table ingress traffic, and one filter applied to the VPLS routing instance flood table ingress traffic.

To apply a Layer 2 port-mirroring firewall filter to the forwarding table or flood table of a VPLS routing instance:

  1. Enable configuration of the VPLS routing instance to which you want to apply a Layer 2 port-mirroring firewall filter for forwarded or flooded traffic:

    For more detailed configuration information, see Configuring a VPLS Routing Instance.
  2. Enable configuration of traffic forwarding on the VPLS routing instance:

  3. Apply a Layer 2 port-mirroring firewall filter to the VPLS routing instance forwarding table or flood table.

    • To mirror packets being forwarded to the VPLS routing instance:

    • To mirror packets being flooded to the VPLS routing instance:

  4. Verify the minimum configuration for applying a Layer 2 port-mirroring firewall filter to the forwarding table or flood table of the VPLS routing instance:
