Let's drop the leading IETF or Infix prefixes from tests. Initially the idea was to mimnic the YANG models, but it's difficult to navigate and does not provide any real benefit to developers or end-users. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>

"""OSPF with multiple areas
|
|
|
|
This test evaluates various OSPF features across three areas (one NSSA area, with no summary)
|
|
to ensure that route distribution is deterministic (based on cost). It also tests link
|
|
failures using BFD, though BFD is not yet implemented in test framework (Infamy).
|
|
|
|
This test also verifies broadcast and point-to-point interface types on /30 network, and
|
|
explicit router-id.
