Configuring a Dynamic MPLS TE Tunnel
Dynamic MPLS TE tunnels are set up using RSVP-TE signaling and are changed according to network changes. On a large-scale network, dynamic MPLS TE tunnels reduce the burden of per-hop configuration. Configuring a dynamic MPLS TE tunnel is the basis for configuring advanced features of MPLS TE.
Pre-configuration Tasks
Before configuring a dynamic MPLS TE tunnel, complete the following tasks:
Configure an IGP to ensure reachable routes between nodes.
Configure an LSR ID for each node.
Enable MPLS globally on each node.
Enable MPLS on each interface of each node.
- Enabling MPLS TE and RSVP-TE
- Configuring an MPLS TE Tunnel Interface
- (Optional) Configuring Link Bandwidth
- Advertising TE Link Information
- (Optional) Configuring Explicit Path for the Tunnel
- Configuring Path Calculation
- (Optional) Disabling TE LSP Flapping Suppression
- Verifying the Dynamic MPLS TE Tunnel Configuration
