Description:
After area range config, summary lsas are aggerated to configured
route but later it was being flushed instead of the actual summary
lsa. This was seen when prefix-id of the aggregated route is same
as one of the actual summary route.
Here, aggregated summary lsa need to be returned to set the flag
SUMMARY_APPROVE after originating aggregated summary lsa but its not.
Which is being cleaned up as part of unapproved summary cleanup.
Corrected this now.

Due to the wrong input argv id, "argv[idx_word]->arg"
fetched in-correctly and it clears all the route-maps instead of
specific one.
Now correct argv id is passed to clear the given route-map counters.
Also, use RMAP_NAME which allows to show list of configured
route-maps in the system.

tl;dr -> Effectively, in this test setup we have 300 dynamic bgp
sessions all of which are using bfd. When a peer collision is detected
or we remove the peers, if an event has been scheduled but not actually
executed yet the event event was not actually being stopped, leaving
the bsp pointer on the thread->arg and causing a crash when it is
executed.

Issue:
When a netns is deleted, since zebra doesn’t receive interface down/delete
notifications from kernel, it manually deletes the interface without removing
the association between zebra_l3vni and the interface that is being deleted
(i.e it deletes the interface without setting “zl3vni->vxlan_if” to NULL).
Later, during the deletion of netns, when zl3vni_rmac_uninstall() is called to
uninstall the remote RMAC from the kernel, zebra ends up accessing stale
“zl3vni->vxlan_if” pointer, which now points to freed memory.
This was causing heap use-after-free.
Fix:
Before zebra starts deleting the interfaces when it receives netns delete notification,
appropriate functions() are being called to remove the association between evpn structs
and interface and set “zl3vni->vxlan_if” to NULL. This ensures that when
zl3vni_rmac_uninstall() is called during netns deletion, it will bail because
“zl3vni->vxlan_if” is NULL.

After restarting pim6d, in some cases the ifindex is 0 for the interfaces,
so the vif index is also assigned as 0.
This causes the interface name to be pim6reg.
Fix:
If the ifindex is 0 and the interface name is not "pimreg" or "pim6reg",
the function will return without assigning vifindex with an error message.

As it can be seen below, the LSDB JSON output varies depending
whether a filter option is specified or not (e.g. "adv-router",
"self-originate"):
> show ip ospf database router json
{
"routerId":"3.3.3.3",
"routerLinkStates":{
"areas":{
"0.0.0.0":[
{
"lsaAge":175,
"options":"*|-|-|-|-|-|E|-",
[snip]
> show ip ospf database router adv-router 2.2.2.2 json
{
"routerId":"3.3.3.3",
"Router Link States":{
"0.0.0.0":{
"2.2.2.2":{
"lsaAge":193,
"options":"*|-|-|-|-|-|E|-",
[snip]
This inconsistency is undesirable since it makes this data harder to
consume programmatically. Also, in the second output, "Router Link
States" is used as a JSON key, which doesn't conform to our JSON
guidelines (JSON keys need to be camelCased).
Make the required changes to ensure the first output structure is used,
regardless if any output filter is used or not.

Before this patch, if we destroy `any` flag for a prefix-list entry, we always
set destination as 0.0.0.0/0 and/or ::/0.
This means that, if we switch from `ip prefix-list r1-2 seq 5 deny any` to
`ip prefix-list r1-2 seq 5 permit 10.10.10.10/32` we will have
`permit any` eventually, which broke ACLs.

Description:
OSPF ABR will summarise the networks based on configured range
and re-advtertise the summarised route. But if configured range
prefix id is same as one of the subset of routes prefix id then
as per rcf2328 Appendex-E recommendation, it will prepare the LSID and originate.
While re-advertising, it is using ospf LSDB instead of area specific
LSDB which is making it fail to re-advertise the summary lsa.
Fixed this by passing correct LSDB pointer.

Imagine this scenario:
A peer has very large hold/keepalive timers of 600/200. This peer is
using the DataCenter default time. As such the open will cause
the t_holdtime to be negotiated to 600 seconds. Now also imagine
that both peers are in update-delay. If we do not restart the
timers and both peers are in Update Delay, we will continously
reset the peer because the hold time will be hit( since the peer
is not sending us any data ).

Reading in prefix-lists is reading in the specified
prefix list and validating that the prefix is unique
2 times. This makes no sense. Relax the requirement
that a prefix list can limit this as well as completely
remove this check. Validation then just becomes
does this prefix-list specified actually make sense
and that is taken care of by the the cli code.
Reading in prefix-lists was looking for duplicate prefixes
2 times instead of doing it just one time. Let's just
not do it at all.
By doing this change, The code changes from never
completing for a 27k long prefix-list to taking
