Spirent TestCenter: Do we have any documentation regarding the maximum number of routes a test module can receive from a DUT?

Environment/Versions
  • Spirent TestCenter.
  • Received routes per test module.
  • BGP.
Answer
Because Spirent TestCenter is primarily concerned with advertising routes to a DUT, we don’t have any documentation regarding the maximum number of routes the test modules can receive.

Below are a couple of things you can try to handle a large number of advertised routes:
  • Enable the Discard Updates option; this way, the test module will discard incoming or received route updates.
  • Increase the Rx Buffer size to the maximum.  The newest STC releases allow up to 8MB, older will allow up to 256KB.

You can find both options at the BGP tab under Settings.
