The route created by the "default-information-originate" command
isn't a regular external route. As such, an NSSA ABR shouldn't
originate a corresponding Type-7 LSA for it (there's a separate
configuration knob to generate Type-7 default routes).

Because vrf backend may be based on namespaces, each vrf can
use in the [16-(2^32-1)] range table identifier for daemons that
request it. Extend the table manager to be hosted by vrf.
That possibility is disabled in the case the vrf backend is vrflite.
In that case, all vrf context use the same table manager instance.
Add a configuration command to be able to configure the wished
range of tables to use. This is a solution that permits to give

Issue #9535 describes how the export-list/import-list commands work
differently on ospfd and ospf6d.
In short:
* On ospfd, "area A.B.C.D export-list" filters which internal
routes an ABR exports to other areas. On ospf6d, instead, that
command filters which inter-area routes an ABR exports to the
configured area (which is quite counter-intuitive). In other words,
both commands do the same but in opposite directions.
* On ospfd, "area A.B.C.D import-list" filters which inter-area
routes an ABR imports into the configured area. On ospf6d, that
command filters which inter-area routes an interior router accepts.
* On both daemons, "area A.B.C.D filter-list prefix NAME <in|out>"
works exactly the same as import/export lists, but using prefix-lists
instead of ACLs.
The inconsistency on how those commands work is undesirable. This
PR proposes to adapt the ospf6d commands to behave like they do
in ospfd.
These changes are obviously backward incompatible and this PR doesn't
propose any mitigation strategy other than warning users about the
changes in the next release notes. Since these ospf6d commands are
undocumented and work in such a peculiar way, it's unlikely many
users will be affected (if any at all).

A bunch of tests have this pattern:
a) Install a new prefix into bgp
b) Run this loop:
foreach (router in topology) {
verify_bgp_rib(router)
}
This is to ensure that the prefix is actually disseminated.
The problem with this, of course, is that a wait of 2 seconds
for every item in that loop makes no sense. As that the initial
router verification of it's bgp rib will wait 2 seconds and
all the remaining bgp routers in the topology will have gotten
the data. So we end up waiting a bunch of extra time.
Remove the initial_wait time for verify_bgp_rib. Also
increase the failure wait time to 30 seconds. This is
to give a bigger window for bgp to send it's data for
our test systems that could be under heavy load. In the
normal case tests will never hit this.

Description:
Change is intended for fixing the following issues related to vrf route leaking:
Routes with special nexthops i.e. blackhole/sink routes when imported,
are not programmed into the FIB and corresponding nexthop is set as 'inactive',
nexthop interface as 'unknown'.
While importing/leaking routes between VRFs, in case of special nexthop(ipv4/ipv6)
once bgp announces route(s) to zebra, nexthop type is incorrectly set as
NEXTHOP_TYPE_IPV6_IFINDEX/NEXTHOP_TYPE_IFINDEX
i.e. directly connected even though we are not able to resolve through an interface.
This leads to nexthop_active_check marking nexthop !NEXTHOP_FLAG_ACTIVE.
Unable to find the active nexthop(s), route is not programmed into the FIB.
Whenever BGP leaks routes, set the correct nexthop type, so that route gets resolved
and correctly programmed into the FIB, in the imported vrf.

There is a possibility that the same line can be matched as a command in
some node and its parent node. In this case, when reading the config,
this line is always executed as a command of the child node.
For example, with the following config:
```
router ospf
network 193.168.0.0/16 area 0
!
mpls ldp
discovery hello interval 111
!
```
Line `mpls ldp` is processed as command `mpls ldp-sync` inside the
`router ospf` node. This leads to a complete loss of `mpls ldp` node
configuration.
To eliminate this issue and all possible similar issues, let's print an

- Get rid of the multiple variables for determining what "Positive" and

- to display on which VRF/view no neighbor was found
Before patch:
ubuntu# show bgp vrf all summary
Instance default:
IPv4 Unicast Summary:
BGP router identifier XX.XX.XX.XX, local AS number XXXX vrf-id 0
(...)
IPv6 Unicast Summary:
Instance private:
IPv4 Unicast Summary:
ubuntu# show bgp vrf all ipv4 multicast summary
% No BGP neighbors found
% No BGP neighbors found
After patch:
ubuntu# show bgp vrf all summary
IPv4 Unicast Summary (VRF default):
BGP router identifier XX.XX.XX.XX, local AS number XXXX vrf-id 0
(...)
IPv6 Unicast Summary (VRF default):
(...)
IPv4 Unicast Summary (VRF private):
(...)
ubuntu# show bgp vrf all ipv4 multicast summary
% No BGP neighbors found in VRF default
% No BGP neighbors found in VRF private

New OSPFv3 NSSA test:
* When a static route is redistributed to an NSSA router it should be
type 7 and should show up in OSPFv3 route database.
* Test LSA Type 7 and route removal.

As this comment says. ZEBRA_FLAG_XXX should not have been used.
To communicate SRv6 Route Information. A simple Nexthop Flag would
have been sufficient for SRv6 information. And I fixed the whole
thing that way.

The "show sharp segment-routing srv6" command was a
json output command, but it did not follow the common
practice of the other commands.
It follows the review and outputs the json format by
using the json keyword. Otherwise, it produces human
readable output.

This commit fix bgpd's prefix-sid type4,5 feature which has
miss implementation from https://github.com/FRRouting/frr/pull/5653
was merged. Due to some nessesary lines are not presented.
When bgpd receives multi update message with same service-sid on
prefix-sid type-5 attribute, bgpd will crash arround path-attribute's
values object reference count.
And also, this commit add a topotest to check that feature work fine.

This commit is a part of #5853 works.
This commit add new topotest to verify SRv6-manager's functionality.
Following tests are performed on this topotest.
- check that SRv6-locator is set correctly
- check that default SRv6-function locator is set correctly
- check that SRv6-function is installed as ipv6 route correctly

This commit checks seg6local route configuration via ZAPI is
working fine.
SRv6 feature is little young feature as kernel feature so netlink
interface may be changed/updated in the future. And this ZAPI extention
is something to support new routing paradigm, so it should be checked by
topotests until srv6 feature of linux kernel will be well stable.

The backoff code assumed that yang operations always completed quickly.
It checked for > 100 YANG modeled commands happening in under 1 second
to enable batching. If 100 yang modeled commands always take longer than
1 second batching is never enabled. This is the exact opposite of what
we want to happen since batching speeds the operations up.
Here are the results for libyang2 code without and with batching.
| action | 1K rts | 2K rts | 1K rts | 2K rts | 20k rts |
| | nobatch | nobatch | batch | batch | batch |
| Add IPv4 | .881 | 1.28 | .703 | 1.04 | 8.16 |
| Add Same IPv4 | 28.7 | 113 | .590 | .860 | 6.09 |
| Rem 1/2 IPv4 | .376 | .442 | .379 | .435 | 1.44 |
| Add Same IPv4 | 28.7 | 113 | .576 | .841 | 6.02 |
| Rem All IPv4 | 17.4 | 71.8 | .559 | .813 | 5.57 |
(IPv6 numbers are basically the same as iPv4, a couple percent slower)
Clearly we need this. Please note the growth (1K to 2K) w/o batching is
non-linear and 100 times slower than batched.
Notes on code: The use of the new `nb_cli_apply_changes_clear_pending`
is to commit any pending changes (including the current one). This is
done when the code would not correctly handle a single diff that
included the current changes with possible following changes. For
example, a "no" command followed by a new value to replace it would be
merged into a change, and the code would not deal well with that. A good
example of this is BGP neighbor peer-group changing. The other use is
after entering a router level (e.g., "router bgp") where the follow-on
command handlers expect that router object to now exists. The code
eventually needs to be cleaned up to not fail in these cases, but that
is for future NB cleanup.

There are two possible use-cases for the `vrf_bind` function:
- bind socket to an interface in a vrf
- bind socket to a vrf device
For the former case, there's one problem - success is returned when the
interface is not found. In that case, the socket is left unbound without
throwing an error.
For the latter case, there are multiple possible problems:
- If the name is not set, then the socket is left unbound (zebra, vrrp).
- If the name is "default" and there's an interface with that name in the
default VRF, then the socket is bound to that interface.
- In most daemons, if the router is configured before the VRF is actually
created, we're trying to open and bind the socket right after the
daemon receives a VRF registration from zebra. We may not receive the
VRF-interface registration from zebra yet at that point. Therefore,
`if_lookup_by_name` fails, and the socket is left unbound.
This commit fixes all the issues and updates the function description.

Add ability to filter session on show bgp summary by neighbor or
remote AS:
ubuntu# show bgp summary ?
neighbor Show only the specified neighbor session
remote-as Show only the specified remote AS session
ubuntu# show bgp summary neighbor ?
A.B.C.D Neighbor to display information about
WORD Neighbor on BGP configured interface
X:X::X:X Neighbor to display information about
ubuntu# show bgp summary remote-as ?
