Spirent TestCenter: Is LSP Ping and Trace Route supported?
Yes Test Center has the capability to send LSP ping to a destination FEC and Trace route as well.
You must enable the LSP-PING technology and activate it and setup the PING parameters under EDIT ECHO Request.
If connecting back to back ports to test you must create LSPs under the LDP tab first.
Then in the LSP ping parameters Inner label set IPv4 Prefix to the LSP address of the destination LDP device.
This places the address inside the payload for the Target FEC Stack
There is also a destination address in the parameters that is used to set the IP header destination address.
I normally set this the same as the LSP address of the destination LDP device but it could have other uses.
Attached is a sample back to back configuration and capture.
