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.
