=== OSPF Default route advertise
|
||||
==== Description
|
||||
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_.
