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 Basic
|
|
|
|
Verifies basic OSPF functionality by configuring two routers (R1 and R2)
|
|
with OSPF on their interconnecting link. The test ensures OSPF
|
|
neighbors are established, routes are exchanged between the routers, and
|
|
end-to-end connectivity is achieved.
|
|
|
|
An end-device (HOST) is connected to R2 on an interface without OSPF enabled.
|
|
This verifies that OSPF status information remains accessible when a router
|
|
has non-OSPF interfaces.
