Example for Configuring the LSP Ping Test for a Common Tunnel
Networking Requirements
In Figure 7-33:
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 and MPLS LDP are enabled on Router A, Router B, and Router C.
MPLS and MPLS LDP are enabled on GE interfaces connected to Router A, Router B, and Router C to trigger the establishment of an LDP LSP.
The NQA LSP Ping test needs to be performed to check the connectivity of the LSP between Router A and Router C.
Configuration Roadmap
The configuration roadmap is as follows:
Configure Router A as the NQA client.
Configure Router C as the NQA server.
Create an LSP Ping test on Router A.
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.
- Configure LDP on RouterA, RouterB,
and RouterC. (The detailed
procedure is not mentioned here.)
For the configuration of LDP, refer to the Huawei AR100&AR120&AR150&AR160&AR200&AR1200&AR2200&AR3200&AR3600 Series Enterprise Routers Configuration Guide - MPLS.
- Configure Router A.
# Enable the NQA client and create an LSP Ping test for a common tunnel.
