- Often millisecond precision is not good enough to differentiate things that
occur directly one after another, and things that have some pause in between,
increase to microsecond precision (reporting)

changes are reflected in r1 and on connectivity between ce1 and c2.

The `bgp_srv6l3vpn_to_bgp_vrf3` topotest tests the SRv6 L3VPN
functionality. It applies the appropriate configuration in `bgpd` and
`zebra`, and then checks that the RIB is updated correctly.
The topotest expects to find the AS-Path in the RIB, which is only
present if the `bgp send-extra-data zebra` option is enabled in the
`bgpd` configuration.
The `bgp send-extra-data zebra` option has been accidentally commented
out in commit 2007e2dbd0.
This commit fixes the `bgp_srv6l3vpn_to_bgp_vrf3` topotest by re-adding
the missing `bgp send-extra-data zebra` option.

Until now, the bgp local paths were using the default null label
defined. It was not possible to select the null label for the ipv4
or the ipv6 address families.
This commit addresses this issues by adding two extra-parameters
to the BGP labeled-unicast command.

`setsockopt()` should be only called once with `MRT_TABLE`
in "enable" case, otherwise it will fail. In current code,
`mroute_socket` of "pim instance" with VRF can't be correctly
closed.
Skip it in the "disable" case to let `mroute_socket` safely
closed.

If r1 becomes the "server" (= local port 179), then it initiates the connection
after sending BGP Notification (BFD Down) and r2 resets the last error code.
Telling r1 do not connect to r2, fixes the issue.
Tested with `pytest -s -n 48` at least 20 times - no failures.

The command `show bgp ipv4 uni neigh A.B.C.D received-routes detail`
was not displaying anything.
Fix the code to display the received routes from the ones that
have been filtered. In this case we need to fudge up a bgp_dest
and a bgp_path_info to make it work.

the ospf_basic_functionality/test_ospf_lan.py script is setting
up a lan env that will have 4 ospf routers on it and shutting/no
shutting interfaces with various priorities to see that ospf
is properly choosing roles. I am consistently seeing the
ospf_basic_functionality/test_ospf_lan.py script failing
where it is saying a neighbor is not in the correct state.
Upon examination of the logs we are seeing this:

This test is setting the dead interval to 4 seconds, seeing a 6 second delay where the os has gone to town
(probably because of the high load on the system ) and not choosing the correct neighbor as the DR.
OSPF when coming up and after seeing the first neighbor, goes into a waiting period before
the DR is elected. If the neighbor does send it's hello packets but they are not processed
before the wait timer pops because of the starvation event, then the wrong neighbor
will be elected DR. Let's give this test a bit more time to decide who the
DR is in case everything goes a bit south.
