Example for Configuring LSP Ping Test for a Common Tunnel
Networking Requirements
In Figure 6-42:
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 and MPLS LDP are enabled on SwitchA, SwitchB, and SwitchC.
MPLS and MPLS LDP are enabled on VLANIF interfaces on SwitchA, SwitchB, and SwitchC 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 SwitchA and SwitchC.
Configuration Roadmap
The configuration roadmap is as follows:
Configure SwitchA as the NQA client.
Configure SwitchC as the NQA server.
Create an LSP Ping test on SwitchA.
Procedure
- Configure SwitchA, SwitchB, and SwitchC and run OSPF to implement reachable routes between
them.
