Example for Configuring the LSP Trace Test for the TE Tunnel
Networking Requirements
In Figure 7-34:
The OSPF protocol runs on Router A, Router B, and Router C. The three Routers learn the 32-bit host routes on their loopback interfaces.
MPLS, MPLS TE, and MPLS RSVP-TE are enabled on Router A, Router B, and Router C.
MPLS, MPLS TE, and MPLS RSVP-TE are enabled on the GE interfaces connected to Router A, Router B, and Router C to set up a TE tunnel from Router A to Router C.
The NQA LSP trace test is used to test the TE tunnel.
Configuration Roadmap
The configuration roadmap is as follows:
Configure Router A as the NQA client. Create an LSP trace test on Router A.
Configure Router C as the NQA server.
Procedure
- Configure reachable routes between Router A and Router B, between Router A and Router C, and between Router B and Router C. The configuration details are not mentioned here.
- Enable MPLS RSVP-TE on Router A, Router B, and Router C. The configuration details
are not mentioned here.
For the configuration of MPLS RSVP-TE, refer to the Huawei AR100&AR120&AR150&AR160&AR200&AR1200&AR2200&AR3200&AR3600 Series Enterprise Routers Configuration Guide - MPLS.
- Configure a TE tunnel on Router A to connect Router C. The configuration details are not mentioned here.
- Create an NQA test on Router A.
