(Optional) Configuring the Traffic Forwarding Function for VLANIF Interfaces

(Optional) Configuring the Traffic Forwarding Function for VLANIF Interfaces

Usage Scenario

By default, VLANIF interfaces do not forward traffic on a multicast VPN extranet, causing traffic interruptions. To resolve this issue, enable the traffic forwarding function for VLANIF interfaces. After this function is enabled, forwarding information on the VLANIF interfaces will be delivered from the VPN routing and forwarding (VRF) table for receivers to the VRF table for multicast sources. Then, the VLANIF interfaces will be capable of forwarding traffic to receivers.

NOTE:

The traffic forwarding function is ineffective for existing multicast entries. To resolve this issue, run the reset multicast forwarding-table command to delete the existing multicast entries. After the multicast entries are regenerated, the traffic forwarding function will become effective for them.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    multicast extranet traffic-forward type vlanif

    The traffic forwarding function is enable for VLANIF interfaces on a multicast VPN extranet.
