Configuring an RSVP-TE Tunnel

Configuring an RSVP-TE Tunnel

MPLS TE reserves resources for RSVP-TE tunnels. These tunnels are established along specified paths, not passing through congested nodes, balancing traffic on a network.

Usage Scenario

The dynamic RSVP-TE signaling protocol adjusts a path of a TE tunnel to adapt to network topology changes. To help implement advanced functions, such as TE FRR or CR-LSP backup, use the RSVP-TE signaling protocol to set up an MPLS TE tunnel.

Pre-configuration Tasks

Before configuring an RSVP-TE tunnel, complete the following tasks:

  • Configure OSPF or IS-IS to implement connectivity between label switching routers (LSRs).

  • Set the LSR ID for every LSR.

  • Enable MPLS in the system and interface views on every LSR.
