Issue:
After vlan flap, zebra was not marking the selected/best route as installed.
As a result, when a static route was configured with nexthop as directly
connected interface's(vlan) IP, the static route was not being installed
in the kernel since its nexthop was unresolved. The nexthop was marked
unresolved because zebra failed to mark the best route as installed after
interface flap.
This was happening because, in dplane_route_update_internal() if the old and
new context type, and nexthop group id are the same, then zebra doesn't send
down a route replace request to kernel. But, the installed (ROUTE_ENTRY_INSTALLED)
flag is set when zebra receives a response from kernel. Since the
request to kernel was being skipped for the route entry, installed flag
was not being set
Fix:
In dplane_route_update_internal() if the old and new context type, and
nexthop group id are the same, then before returning, installed flag will
be set on the route-entry if it's not set already.

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.
Let's just not allow the command to succeed in this case as that
the test was wrong.

When a `no router bgp XXX` is issued and the bgp instance
is in the process of shutting down, do not allow a l3vni
change coming up from zebra to do anything. We can just
safely ignore it at this point in time.

Topology Used:
=============
Cisco---FRR4----FRR2
Initially PIM nbr is down between FRR4----FRR2 from FRR2 side
Cisco is sending BSR packet to FRR4.
Problem Statement:
=================
No shutdown the PIM neighbor on FRR2 towards FRR4.
FRR2, receives BSR packet immediately as the new neighbor
comes up. This BSR packet is having no-forward bit set.
FRR2 is not able to process the BSR packet, and drop the
BSR packet.
Root Cause:
==========
When PIMD comes up, we start BSM timer for 60 seconds.
Here, the value accept_nofwd_bsm is setting to false.
FRR2, when receives no-forward BSR packet, it is getting
accept_nofwd_bsm value as false.
So, it drops, the no-forward BSM packet.
Fix:
===
Set accept_nofwd_bsm as false after first BSM packet received.

update_type1_routes_for_evi() is called from
L3VNI/L2VNI up event, if ESI is not UP then
do not advertise EAD-ES Type-1 route.
Just like from multiple places EAD-ES route
origination checks for its oper status.
