The purpose of this test is to check if Equal Cost MultiPath (ECMP) Routes are being built and used correctly.

Constructor & Destructor Documentation

RandomEcmpTestCase::RandomEcmpTestCase ( )

void RandomEcmpTestCase::BuildLsa ( )

private

Builds the LSAs for the topology.

These LSAs are manually created and inserted into the GlobalRouteManagerLSDB.Each node exports a router LSA.
