Currently the Wait for Install code ( bgp_suppress_fib ) does
not properly handle two states from zebra: ROUTE_INSTALL_FAILED
and BETTER_ADMIN_DISTANCE_WON. Pre this change the WFI code
would just never notify our peers about a route install failure
but more is needed. In the ROUTE_INSTALL_FAILED and the
BETTER_ADMIN_DISTANCE_WON we need to notify our peers with
a withdrawal about the route, else we will continue to
draw traffic to us when we cannot legally do so.
Why is this needed? In either case imagine that we've already
received a bgp route, installed it and sent to our peers.
In the Better admin distance won case, say a static route is installed
at this point in time we must stop advertising the route through
us since we are not installed. As such a withdrawal must be sent.
In the ROUTE_INSTALL_FAILED case, the code was not properly handling
the situation where we have Route A, it was successfully installed
and then we received a update to Route A that was attempted to be
installed but failed. In this case we also need to send a withdrawal
Finally update the bgp_suppress_fib topotest to test both of these
situations.

Duplicate a couple of definitions in order to remove the bgpd
includes from this libfrr header. This is necessary to fix some
name collisions like PREFIX_LIST_IN being defined differently on

Including daemon headers on libfrr headers is a bad practice and

We should always treat the VRF interface as a loopback. Currently, this
is not the case, because in some old pre-VRF code we use if_is_loopback
instead of if_is_loopback_or_vrf. To avoid any future problems, the
proposal is to rename if_is_loopback_or_vrf to if_is_loopback and use it
everywhere. if_is_loopback is renamed to if_is_loopback_exact in case
it's ever needed, but currently it's not used anywhere.

This removes a giant `switch { }` block from lib/zclient.c and
harmonizes all zclient callback function types to be the same (some had
a subset of the args, some had a void return, now they all have
ZAPI_CALLBACK_ARGS and int return.)
Apart from getting rid of the giant switch, this is a minor security
benefit since the function pointers are now in a `const` array, so they
can't be overwritten by e.g. heap overflows for code execution anymore.

With v6 interface based peering, we send the global as well as the LL address
as nexthops to the peer. When either of these were removed on the interface
we were not necessarily resetting the connection. Leaving bgp in a state
where the peer had reachability for addresses that are no longer in use.
Modify the code that when we receive an interface address deletion
event. Check to see that we are using the v6 address as nexthops
for that peer and if so, tell it to reset.
I initially struggled with a hard reset of the peer or a clear but
choose to follow other places in the code that we noticed address
changes that resulted in hard resets.

Description:
Change is intended for fixing the following issues related to vrf route leaking:
Routes with special nexthops i.e. blackhole/sink routes when imported,
are not programmed into the FIB and corresponding nexthop is set as 'inactive',
nexthop interface as 'unknown'.
While importing/leaking routes between VRFs, in case of special nexthop(ipv4/ipv6)
once bgp announces route(s) to zebra, nexthop type is incorrectly set as
NEXTHOP_TYPE_IPV6_IFINDEX/NEXTHOP_TYPE_IFINDEX
i.e. directly connected even though we are not able to resolve through an interface.
This leads to nexthop_active_check marking nexthop !NEXTHOP_FLAG_ACTIVE.
Unable to find the active nexthop(s), route is not programmed into the FIB.
Whenever BGP leaks routes, set the correct nexthop type, so that route gets resolved
and correctly programmed into the FIB, in the imported vrf.

When setting bgp configuration using peers referencing link local
ipv6 addresses, the bgp should be able to handle incoming bgp
connections, and find out the appropriate interface where the
connection comes from.
ipv6 link local sessions work by using bgp unnumbered interfaces
config, but it does not work if we have a shared media with
multiple potential link local ipv6 addresses on the network.
The fix consists in finding out the appropriate interface, when
the local configuration references a link local ipv6 addresses,
and the source address used references an interface. below
configuration illustrates what can be done then:
neighbor fe80::4113:5bba:2b61:b20c remote-as 55
neighbor fe80::4113:5bba:2b61:b20c update-source eth0
note: this change does not solve the ability for such config to
create an outgoing connection to remote peer (as the link local
ipv6 address config does not indicate which interface to use).

The BFD function `bgp_bfd_is_peer_multihop` will no longer exist and now
both code paths are equal.
Longer explanation:
Cumulus was previously using the BFD function to help determine whether a
peer is multi hop or not, because there is a configuration to set BFD
to use single or multi hop.
Current BFD code can automatically pick between single/multi hop by
using the protocol information and so it is a good idea to have that
tested/used than relying on yet another duplicated information.
(BFD extracts the TTL information from protocol and selects
single/multi hop based on that)

a) zebra does not properly track multiple prefixes that match

b) BGP was receiving nexthops that were just incorrect because
of (a).
c) When a nexthop changed that really didn't affect the v6 LL

DF (Designated forwarder) election is used for picking a single
BUM-traffic forwarded per-ES. RFC7432 specifies a mechanism called
service carving for DF election. However that mechanism has many
disadvantages -
1. LBs poorly.
2. Doesn't allow for a controlled failover needed in upgrade
scenarios.
3. Not easy to hw accelerate.
To fix the poor performance of service carving alternate DF mechanisms
have been proposed via the following drafts -
draft-ietf-bess-evpn-df-election-framework
draft-ietf-bess-evpn-pref-df
This commit adds support for the pref-df election mechanism which
is used as the default. Other mechanisms including service-carving
may be added later.
In this mechanism one switch on an ES is elected as DF based on the
preference value; higher preference wins with IP address acting
as the tie-breaker (lower-IP wins if pref value is the same).
