When a interface is configured as BGP unnumbered, it
has a v6 LL address as well as no v4 addresses. In
this case let's look at the lo's ip address as the
primary address to use.

This fix allows the RP to transition from a Prune'd to Join
state on reception of proper control messages.
Additionally it was noticed on if down -> if up transitions
the prune then join message was going out the wrong interface.

I tried to be smart and skirt around rpf lookup if I knew
the incoming interface. This turns out to be not necessarily
a good thing because we can easily have asymetrical routing.
This fix removes the attempt to cache the ifp we received
the incoming packet on and just lets the lookup work like
it should.
Additionally it removes the weird hardcoding of the rpf
interface from the register stuff.

reb
When on a intermediate switch between the FHR and RP
when Quagga is restarted. Pimd is coming up so fast
and getting the S,G join before networking is properly
working on the switch. We would never install the
mroute in this case.
What was happening is that the scan of the S,G was
occurring and we were figuring out who we should talk
to but we were never installing the route for it.
Notice that we've never installed the route and install it
if the mroute has changed.

pim_zebra.c was checking to see if a ifp pointer was null
in some debug statements. This caused the SA code
to assume that if we were at this point then the ifp
could be null and subsuquent code that doesn't check
for it to be wrong.

Allow the user to specify multiple rp commands.
'ip pim rp A.B.C.D' -> translates to 'ip pim rp A.G.C.D 224.0.0.0/24'
ip pim rp A.B.C.D A.B.C.D/M
First is the rp, second is the group with mask.
Groups and masks cannot be over each other except 224.0.0.0/24 which
is the fallback if used.

This patch improves zebra,ripd,ripngd,ospfd and bgpd so that they can
make use of 32-bit route tags in the case of zebra,ospf,bgp or 16-bit
route-tags in the case of ripd,ripngd.
It is based on the following patch:

Since recently zebra uses only the ZEBRA_REDISTRIBUTE_* messages
to advertise redistributed routes to its clientes. Now the old
ZEBRA_IPV*_ROUTE_* messages are only used for client->zebra communication.

When a multicast route's rpf changes( for whatever reason ) (*,G)
routes were never updating properly. This is because we were
attempting to fing the path to the *, instead of the RP.
Modify the code to check if we are attempting to find a

Welcome pimd to the Quagga daemon zoo!
This is a merge of commit 77ae369 ("pimd: Log ifindex found for an
interface when zebra lib reports a new connected address."), with
the intermediate "reconnect" changes removed (c9adf00...d274381).
d274381 is replaced with b162ab7, which includes some changes. In
addition, 4 reconnect-related changes and 1 cosmetic one have been
bumped out.
The rebase command used to produce the branch that is merged here is:
git rebase --onto b162ab7 c9adf00 77ae369

"Anonymous SR#108542 <>" (which is not a valid git author ID)
