The test is testing whether interface flaps are causing
the appropriate pim reactions. Unfortunately the test
is turning off the multicast stream and the test also
has a keep alive timer of 15 seconds set on all routers.
Which of course means the test has 15 seconds(at most) to finish
testing. This is not always possible given system loads.

The test_multicast_pim_sm_topo3.py test is both spending extra time
looking for state that will never occurr but also generating a support
bundle when it doesn't find it. Fix the test to come to the correct

And FRR does a link flap, it refigures the route and rejects the default
route:

So the 192.168.212.1 route is matched for the nexthop but it is not connected and
zebra treats it as a problem. Modify the code such that if a system route
matches through another system route, then it should work imo.

When watchfrr has noticed issues, send operational state
to systemd so operators issuing `systemd status frr` can
see a more nuanced state of the daemon.
Add the `--operational-timeout X` value to the cli. After
the daemon has been restarted and communication re-established
wait this time before reporting to systemd that the daemon
is up and running.
Default value of 60 seconds was choosen to allow some small
delay in reporting so that, if the daemon is in a crash loop
status will not ping pong.

When the peer is configured for the first time:
```
neighbor P1 peer-group
neighbor P1 remote-as external
neighbor P1 advertise-map ADV exist-map EXIST
neighbor 10.10.10.1 peer-group P1
```
Conditional advertisements route-maps are not updated and cond. advertisements
do not work until FRR restarted. BGP sessions clear does not help.
Or even changing peer-group for a peer, causes this bug to kick in.
```
no neighbor 10.10.10.1
neighbor 10.10.10.1 peer-group P2
```
With this fix, cond. advertisements start working immediatelly.

Add a test case to ensure that Kernel routes are not lost
when there are multiple overlapping connected routes.
Signed-off-by: Donald Sharp <sharpd@nvidia.com>
This bug should only really affect kernel routes. To reproduce:
a) Have multiple connected routes that point to the same prefix
swp8 up default 169.254.0.250/30
swp9 up default 169.254.0.250/30
b) Have a kernel route that uses one of those connected routes
7.6.2.8 via 169.254.0.249 dev swp8 proto static
(But have it choose a non-selected connected nexthop)
c) Introduce an event that causes the rib table to be reprocessed,
say a unrelated interface going up / down
This causes the route to be lost with this message:
2022/03/28 21:21:53 ZEBRA: [YXCJP-0WZWV] netlink_nexthop_msg_encode: ID (3454): 169.254.0.249, via swp8(1383) vrf default(0)
2022/03/28 21:21:53 ZEBRA: [YF2E6-J60JH] nexthop_active: 169.254.0.249, via swp8 given ifindex does not match nexthops ifindex found found: directly connected, swp9
Effectively the nexthop that zebra is choosing would not be the one
that the kernel route has choosen and FRR removes the route:
022/03/28 21:21:53 ZEBRA: [NM15X-X83N9] rib_process: (0:254):7.6.2.8/32: rn 0x56042e632e90, removing re 0x56042e6316e0
2022/03/28 21:21:53 ZEBRA: [Y53JX-CBC5H] rib_unlink: (0:254):7.6.2.8/32: rn 0x56042e632e90, re 0x56042e6316e0
2022/03/28 21:21:53 ZEBRA: [KT8QQ-45WQ0] rib_gc_dest: (0:?):7.6.2.8/32: removing dest from table
What is happening?
Zebra is not looking at all connected routes and if any of them
would have the appropriate ifindex and just blindly rejecting
the route.
So when nexthop resolution happens and it matches a connected
route and the dest->selected nexthop ifindex does not match, let's sort
through the rest of them and see if any of them match and if so
let's keep the route.
