The scale_up.py script used by several tests installs 50k routes into the rib from

that the routes are actually installed into the rib first before looking in
the bgp tables. This should help situations where the system is under extreme

bgpd: add cli command to control explicit-null label usage
In BGP labeled unicast address-family, it is not possible to
send explicit-null label values with redistributed or network
declared prefixes.
A new CLI command is introduced:
> [no] bgp labeled-unicast explicit-null
When used, the explicit-null value for IPv4 ('0' value) or
IPv6 ('2' value) will be used.
It is necessary to reconfigure the networks or the
redistribution in order to inherit this new behaviour.
Add the documentation.

Locally, the bgp_evpn_vxlan_svd_topo1 and bgp_evpn_vxlan_topo1

bgpd: Do not allow a `no router bgp XXX` when autoimport is happening
When we have these sequence of events causing a crash in
evpn_type5_test_topo1:
(A) no router bgp vrf RED 100
this schedules for deletion the vrf RED instance
(B) a l3vni change event from zebra
this creates a bgp instance for VRF RED in some cases
additionally it auto imports evpn routes into VRF RED
Please note this is desired behavior to allow for the
auto importation of evpn vrf routes
(C) no router bgp 100
The code was allowing the deletion of the default
instance and causing tests to crash.
Effectively the test in bgp_vty to allow/dissallow
the removal of the default instance was not correct
for the case when (B) happens.

Currently the process of the `route-map` configuration for `per-vrf-rip`
is wrong.
There are two problems:
1. `ctx->name` for `if_rmap_ctx` is not initialized in `if_rmap_ctx_create()`.
2. The global `if_rmap_ctx_list` is wrongly used for `per-vrf-rip`.
So, two changes for it:
1. Correctly initializes `ctx->name`.
2. Use specific `if_rmap_ctx` for `per-vrf-rip`, not global one.
Note, this related implementation for `route-map` is only for `ripd`.

ospfd: add support for NSSA Type-7 address ranges
Implement NSSA address ranges as specified by RFC 3101:
NSSA border routers may be configured with Type-7 address ranges.
Each Type-7 address range is defined as an [address,mask] pair. Many
separate Type-7 networks may fall into a single Type-7 address range,
just as a subnetted network is composed of many separate subnets.
NSSA border routers may aggregate Type-7 routes by advertising a
single Type-5 LSA for each Type-7 address range. The Type-5 LSA
resulting from a Type-7 address range match will be distributed to
all Type-5 capable areas.
Syntax:
area A.B.C.D nssa range A.B.C.D/M [<not-advertise|cost (0-16777215)>]
Example:
router ospf
router-id 1.1.1.1
area 1 nssa
area 1 nssa range 172.16.0.0/16
area 1 nssa range 10.1.0.0/16
!
Since regular area ranges and NSSA ranges have a lot in common,
this commit reuses the existing infrastructure for area ranges as
much as possible to avoid code duplication.
