Rearrange the ripngd northbound callbacks as following:
* ripng_nb.h: prototypes of all northbound callbacks.
* ripng_nb.c: definition of all northbound callbacks and their
associated YANG data paths.
* ripng_nb_config.c: implementation of YANG configuration nodes.
* ripng_nb_state.c: implementation of YANG state nodes.
* ripng_nb_rpcs.c: implementation of YANG RPCs.
This should help to keep to code more organized and easier to
maintain.
No behavior changes intended.

* Turn the "instance" YANG presence-container into a YANG list keyed
by the new "vrf" leaf. This is a backward incompatible change but
this should be ok for now.
* RIPng VRF instances can be configured even when the corresponding
VRF doesn't exist. And a RIPng VRF instance isn't deleted when
the corresponding VRF is deleted. For this to work, implement the
ripng_instance_enable() and ripng_instance_disable() functions
that are called to enable/disable RIPng routing instances when
necessary. A RIPng routing instance can be enabled only when the
corresponding VRF is enabled (this information comes from zebra
and depends on the underlying VRF backend). Routing instances are
stored in the new ripng_instances rb-tree (global variable).
* Add a vrf pointer to the ripng structure instead of storing vrf_id
only. This is much more convenient than using vrf_lookup_by_id()
every time we need to get the vrf pointer from the VRF ID. The
ripng->vrf pointer is updated whenever the VRF enable/disable hooks
are called.

This is the last step to make ripngd ready for multi-instance
support.
Remove the ripng global variable and add a "ripng" parameter
to all functions that need to know the RIPng instance they are
working on. On some functions, retrieve the RIPng instance from
the interface variable when it exists (this assumes interfaces can
pertain to one RIPng instance at most, which is ok for VRF support).
In preparation for the next commits (VRF support), add a "vrd_id"
member to the ripng structure, and use ripng->vrf_id instead of
VRF_DEFAULT wherever possible.

* Call ripng_clean() only when RIPng is configured, this way we can
remove one indentation level from this function.
* ripng_redistribute_clean() is only called on shutdown, so there's
no need to call ripng_redistribute_withdraw() there since the RIPng
table is already cleaned up elsewhere.
* Deallocate the ripng structure only at the end of the function. This
prepares the ground for the next commits where all global variables
will be moved to the ripng structure.

Now that all ripngd commands were converted to the new northbound
model, the ripngd SIGHUP handler is capable of doing a full
configuration reload just by calling the vty_read_config()
function. Nothing else should be done in the SIGHUP handler.

Introduce frr-ripngd.yang, which defines a model for managing the

Update the 'frr_yang_module_info' array of ripngd with the new

Add two new files (ripng_cli.[ch]) which should contain all ripngd

The Vrf aliases can be known with a specific hook. That hook will then,

This option is only implemented by 4 daemons:
- BGPD
- RIPD
- RIPNGD
- Zebra
Manpages and documentation say that the option causes routes to not be
uninstalled from zebra when the daemon terminates. This is true for RIPD
and RIPNGD. This is not true for BGPD; in that daemon it only prevents
transmission of Cease / Peer Unconfig NOTIFICATION messages to peers.
Moreover, when any daemon disconnects from Zebra, all of its routes are
uninstalled from Zebra and the kernel regardless of this option,
rendering the option largely vestigial.
It is still useful in Zebra, where it prevents all routes from being
uninstalled when Zebra shuts down, so it is left there.

The FSF's address changed, and we had a mixture of comment styles for
the GPL file header. (The style with * at the beginning won out with
580 to 141 in existing files.)
Note: I've intentionally left intact other "variations" of the copyright
header, e.g. whether it says "Zebra", "Quagga", "FRR", or nothing.

to capture log entries if no log file is defined. This also allows the
capture of logged information prior to reading each daemon's config file.

environments. This needs to be done in SysV and systemd
startups. As such refactor the code to allow us to
allow end users to easily switch between the two
sysV:
edit the /etc/quagga/daemons file
service quagga [start|stop|reload|restart]
Systemd:

Later, an interface will belong to a specific VRF, and the interface
initialization will be a part of the VRF initialization. So now call
if_init() from vrf_init(), and if_terminate() from vrf_terminate().
Daemons have the according changes:
- if if_init() was called or "iflist" was initialized, now call
vrf_init() instead;
- if if_terminate() was called or "iflist" was destroyed, now call
vrf_terminate() instead.

——————————————-------------
- etc/init.d/quagga is modified to support creating separate ospf daemon
process for each instance. Each individual instance is monitored by
watchquagga just like any protocol daemons.(requires initd-mi.patch).
- Vtysh is modified to able to connect to multiple daemons of the same
protocol (supported for OSPF only for now).
- ospfd is modified to remember the Instance-ID that its invoked with. For
the entire life of the process it caters to any command request that
matches that instance-ID (unless its a non instance specific command).
Routes/messages to zebra are tagged with instance-ID.
- zebra route/redistribute mechanisms are modified to work with
[protocol type + instance-id]
- bgpd now has ability to have multiple instance specific redistribution
for a protocol (OSPF only supported/tested for now).
- zlog ability to display instance-id besides the protocol/daemon name.
- Changes in other daemons are to because of the needed integration with
some of the modified APIs/routines. (Didn’t prefer replicating too many
separate instance specific APIs.)
- config/show/debug commands are modified to take instance-id argument
as appropriate.
Guidelines to start using multi-instance ospf
---------------------------------------------
The patch is backward compatible, i.e for any previous way of single ospf
deamon(router ospf <cr>) will continue to work as is, including all the
show commands etc.
To enable multiple instances, do the following:
1. service quagga stop
2. Modify /etc/quagga/daemons to add instance-ids of each desired
instance in the following format:
ospfd=“yes"
ospfd_instances="1,2,3"
assuming you want to enable 3 instances with those instance ids.
3. Create corresponding ospfd config files as ospfd-1.conf, ospfd-2.conf
and ospfd-3.conf.
4. service quagga start/restart
5. Verify that the deamons are started as expected. You should see
ospfd started with -n <instance-id> option.
ps –ef | grep quagga
With that /var/run/quagga/ should have ospfd-<instance-id>.pid and
ospfd-<instance-id>/vty to each instance.
6. vtysh to work with instances as you would with any other deamons.
7. Overall most quagga semantics are the same working with the instance
deamon, like it is for any other daemon.
NOTE:
To safeguard against errors leading to too many processes getting invoked,
a hard limit on number of instance-ids is in place, currently its 5.
Allowed instance-id range is <1-65535>
Once daemons are up, show running from vtysh should show the instance-id
of each daemon as 'router ospf <instance-id>’ (without needing explicit
configuration)
Instance-id can not be changed via vtysh, other router ospf configuration
is allowed as before.
