Spirent TestCenter : Why are my LSPs not appearing in DUT even when the LDP counters say they were advertised?


Scenario: STC port connected to a DUT.

LDP session is established between DUT and 2 Simulated devices in STC port.

STC devices advertise 100 prefixes each, counters verify that 2000 prefixes were advertised. 

Issue: DUT shows only 1900 prefixes, 100 are missing.

Resolution: Use discontinuous network prefixes on both STC devices. They appeared to be overlapping for some addresses.
