Configuring P2MP TE Tunnels with Dual-Root Protection

This section describes how to configure P2MP TE tunnels with dual-root protection to ensure the reliable transmission of multicast traffic.

Procedure

Perform the following steps on each root node:
1. Run system-view
  The system view is displayed.
2. Run vsi vsi-name
  A VSI is created, and the VSI view is displayed.
3. (Optional) Run ignore-ac-state
  The VSI is configured to ignore AC status changes.
4. Run inclusive-provider-tunnel
  The VSI-Inclusive view is created and displayed.
5. Run root
  The current device is specified as the root node for multicast VPLS, and the VSI-Inclusive-Root view is displayed.
6. Run data-switch disable
  The current device is disabled from transmitting multicast traffic over P2P tunnels when the P2MP TE tunnel is Down.
7. (Optional) Run bfd track interface interface-type interface-number
  BFD is configured to monitor the upstream AC interface.
8. Run mpls-te
  The tunnel type is specified as P2MP TE for the local VSI, and the VSI-Inclusive-Root-TE view is displayed.
9. Run p2mp { dynamic | te-template template-name }
  A P2MP TE tunnel is created.
10. Run commit
  The configuration is committed.
Perform the following steps on each leaf node:
1. Run system-view
  The system view is displayed.
2. Run vsi vsi-name
  A VSI is created, and the VSI view is displayed.
3. Run inclusive-provider-tunnel
  The VSI-Inclusive view is created and displayed.
4. Run leaf
  The current device is specified as a leaf node for multicast VPLS.
5. Run primary-root priRootIp [ trackbfd ] backup-rootbakRootIp [ trackbfd ] [ wtrwtrValue ]
  The primary and backup P2MP TE tunnels are specified.
6. Run commit
  The configuration is committed.
