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 Default route advertise
|
|
|
|
Verify _default-route-advertising_ in OSPF, sometimes called 'redistribute origin'. Verify both
|
|
always (regardless if a local default route exist or not) and only redistribute
|
|
when local default route exist.
|
|
|
|
The test is performed by setting a default route on R1 to 192.168.10.2, and setting
|
|
_default-route-advertising_ in OSPF, this will result that R2 will see a default route.
|
|
|
|
When set interface R1:data down, OSPF will no longer redistribute default route to R2,
|
|
unless _always_ is set for _default-route-advertising_.
