During the time the `ospf_abr_nssa_check_status()` function is not executed,
we are in a situation where the role is OSPF_NSSA_ROLE_NEVER (just configured)

If we enter:

This will crash ospf. Prevent this from happening.
OSPF instances:
a) Cannot be mixed with non-instance
b) Are their own process.
Since in multi-instance world ospf instances are their own process,
when an ospf processes receives an instance command we must remove
our config( if present ) and allow the new config to be active
in the new process. The problem here is that if you have not
done a `router ospf` above the lookup of the ospf pointer will
fail and we will just crash. Put some code in to prevent a crash

Field vrf_id is replaced by the pointer of the struct vrf *.
For that all other code referencing to (interface)->vrf_id is replaced.
This work should not change the behaviour.
It is just a continuation work toward having an interface API handling
vrf pointer only.
some new generic functions are created in vrf:
vrf_to_id, vrf_to_name,
a zebra function is also created:
zvrf_info_lookup
an ospf function is also created:
ospf_lookup_by_vrf
it is to be noted that now that interface has a vrf pointer, some more
optimisations could be thought through all the rest of the code. as
example, many structure store the vrf_id. those structures could get
the exact vrf structure if inherited from an interface vrf context.

The frr-interface YANG module models interfaces using a YANG list keyed
by the interface name and the interface VRF. Interfaces can't be keyed
only by their name since interface names might not be globally unique
when the netns VRF backend is in use. When using the VRF-Lite backend,
however, interface names *must* be globally unique. In this case, we need
to validate the uniqueness of interface names inside the appropriate
northbound callback since this constraint can't be expressed in the
YANG language. We must also ensure that only inactive interfaces can be
removed, among other things we need to validate in the northbound layer.

output if the instance existed but no neighbors were defined. This
fix makes these commands more consistent in returning empty braces for
json output and issue a message if not using json output. Additionally,

it had been defined as an int, char, u_char, and bool at various places.

This is an important optimization for users running FRR on systems with
a large number of interfaces (e.g. thousands of tunnels). Red-black
trees scale much better than sorted linked-lists and also store the
elements in an ordered way (contrary to hash tables).
This is a big patch but the interesting bits are all in lib/if.[ch].

Multi-Instance OSPF configuration CLI would fail because
first client return error upon seeing qobj_index being 0.
With new marco generate new error code to return from each
instance (vtysh client) and if the command is intended for given
instance, its qobj_index would be nonzero and process the command
and push correct ospf context. Other instance would return the error.
On vtysh end, check all instance return an error log a message to a

ospfd: Extend 'ip ospf area' to take address argument + rationalise ospf enable
* ospfd.c: (general) Clean up the whole running of OSPF on interfaces.
(add_ospf_interface) taking (struct interface *) arg is pointless here.
(ospf_is_ready) new helper.
(ospf_network_run_subnet) Put all the code for choosing whether to enable
OSPF on a subnet, and if so which area configuration to use, here. If a
subnet should not be enabled, ensure an existing oi is freed.
(ospf_network_run_interface) Just call run_subnet for all subnets on an
interface.
(ospf_network_run) Just call run_interface for all interfaces.
(ospf_if_update) Just call run_interface for the given interface.
(ospf_network_unset) Just call run_subnet for existing ois.
(ospf_update_interface_area) helper: update area on an oi, or create it.
(ospf_interface_set) renamed to ospf_interface_area_set for clarity.
Ensures OSPF is created, then into if_update.
(ospf_interface_unset) renamed to ospf_interface_area_unset and collapses
down to simple loop to call run_subnet for all ois.
* ospf_interface.h: add a more general OSPF_IF_PARAM_IS_SET, which does the
right thing and takes default config into account.
* doc/ospfd.texi: add 'ip ospf area' command.

This patch has been part of Quagga since October 2015

log.c provides functionality for associating a constant (typically a
protocol constant) with a string and finding the string given the
constant. However this is highly delicate code that is extremely prone
to stack overflows and off-by-one's due to requiring the developer to
always remember to update the array size constant and to do so correctly
which, as shown by example, is never a good idea.b
The original goal of this code was to try to implement lookups in O(1)
time without a linear search through the message array. Since this code
is used 99% of the time for debugs, it's worth the 5-6 additional cmp's
worst case if it means we avoid explitable bugs due to oversights...
