Constructor & Destructor Documentation

RandomEcmpTestCase::RandomEcmpTestCase ( )

Here is the call graph for this function:

void RandomEcmpTestCase::BuildLsav4 ( )

private

Builds the LSAs for the topology.

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