Fixes: #10939
Signed-off-by: Donald Sharp <sharpd@nvidia.com>
That commit aim is to fix an invalid behavior when
default-information is activated on ospf router without always option.
Consider an ASBR with:
-one default route coming from ospf,
-and another default route coming from another deaemon (such BGP or static).
When the daemon bgp stops advertising its default route,
-ospf continues to advertise its previous default route (with aging 0),
-this may create default routing loops.
Expected behavior: is to update the removed external default route with
MAXAGING value.
Updating with MAXAGING value will notify the fact the route is currently
invalid. A later removal from ospf external LSA database will be made.
Analysis: all default routes have their type overwritten by a
DEFAULT_ROUTE type. Thus all default routes whatever its origin (ospf,
bgp, static...) is treated in a same way. But this is not pertinent for
ospf originated default routes.
Fix: avoid overwiting of route type when default route is ospf type.

Description:
Default route is not getting flushed from neighbours though originator
triggered flush and deleted LSA from its database. It become as stale
LSA in neighbours databse forever. This could seen in the following
sequence of configurations with less than a second interval b/w configs.
And this could happen only when originator shouldnt have default route
in its rib so it originates default route only when configure with 'always'
option.
step-1:default-information originate always
step-2:no default-information originate always
step-3:default-information originate
In step-1, default route will be originated to AS.
In step-2, default route will be flushed to AS, but neighbours will be
discarding this update due to minlsainterval condition.
And it is expected that DUT need to keep send this update
until it receives the ack from neighbours by adding each
neighbour's retransmission list.
In Step-3: It is deleting the lsas from nbr's retransmission list
by assuming it initiated the flush. This is cuasing to not
send the lsa update anymore to neighbours which makes
stale lsa in nbrs forever.
Fix:
Allowed to delete the lsa from retransmission list only when lsa is
not in maxage during flushing procedure.

Description:
This LSID alogithm added as per rcf2328 Appendex-E recommendation.
This applies only for AS-external lsas and summary lsas.
As an example of the algorithm, consider its operation when the
following sequence of events occurs in a single router (Router A).
(1) Router A wants to originate an AS-external-LSA for
[10.0.0.0,255.255.255.0]:
(a) A Link State ID of 10.0.0.0 is used.
(2) Router A then wants to originate an AS-external-LSA for
[10.0.0.0,255.255.0.0]:
(a) The LSA for [10.0.0,0,255.255.255.0] is reoriginated using a
new Link State ID of 10.0.0.255.
(b) A Link State ID of 10.0.0.0 is used for
[10.0.0.0,255.255.0.0].
(3) Router A then wants to originate an AS-external-LSA for
[10.0.0.0,255.0.0.0]:
(a) The LSA for [10.0.0.0,255.255.0.0] is reoriginated using a
new Link State ID of 10.0.255.255.
(b) A Link State ID of 10.0.0.0 is used for
[10.0.0.0,255.0.0.0].
(c) The network [10.0.0.0,255.255.255.0] keeps its Link State ID
of 10.0.0.255.

The ospf instance code is not properly handling the default route
when using default-information originate. This is because
the code is looking for the default route to be saved with an
instance of <ospf instance id> but we always save it as a instance
id of 0. In fact OSPF asks zebra for the default route as a special
case in instance 0, always.
Here is the correct behavior:
