Configuring Multicast Fast Switch in a VPLS over TE Scenario
Multicast fast switch can fast switch VSI multicast traffic from a faulty primary TE tunnel to a backup tunnel. Multicast fast switch can be enabled in VPLS over TE scenarios in which the public network tunnels of a VSI are TE tunnels and the VSI forwards multicast traffic.
Applicable Environment
Multicast fast switch can fast switch VSI multicast traffic from a primary TE tunnel that fails to a backup tunnel. Multicast fast switch can be enabled in VPLS over TE scenarios in which the public network tunnels of a VSI are TE tunnels and the VSI forwards multicast traffic.
Multicast fast switch in a VPLS over TE scenario can be implemented between a TE tunnel and an FRR bypass tunnel, between a TE tunnel and a hot standby (HSB) tunnel, or between primary and backup TE tunnels.
Pre-configuration Tasks
Before configuring multicast fast switch in a VPLS over TE scenario, complete the following tasks:
Connect interfaces and set physical parameters to ensure that the physical interface status is Up.
Configure a primary MPLS TE tunnel.
Configure BFD for the primary MPLS TE tunnel.
Configure a backup MPLS TE tunnel.
Configure basic VPLS functions.
Create a VSI.
Configure a tunnel policy for the VSI.
Procedure
- Run system-view
