Example for Configuring LSP Trace Test for a TE Tunnel
Networking Requirements
In Figure 6-45:
The OSPF protocol runs on SwitchA, SwitchB, and SwitchC. They have learned the 32-bit host routes of each other on their loopback interfaces.
MPLS, MPLS TE, and MPLS RSVP-TE are enabled on SwitchA, SwitchB, and SwitchC.
MPLS, MPLS TE, and MPLS RSVP-TE are enabled on the VLANIF interfaces on SwitchA, SwitchB, and SwitchC to set up a TE tunnel from SwitchA to SwitchC.
An NQA LSP Trace test needs to be performed for the TE tunnel.
Configuration Roadmap
The configuration roadmap is as follows:
Configure SwitchA as the NQA client and create an LSP Trace test instance on SwitchA.
Configure SwitchC as the NQA server.
Procedure
- Configure SwitchA, SwitchB, and SwitchC and run OSPF to implement reachable routes between
them.
