In a data center, having 32-128 peers is not uncommon. In such a situation, to find a
peer that has failed and why is several commands. This hinders both the automatability of
failure detection and the ease/speed with which the reason can be found. To simplify this
process of catching a failure and its cause quicker, this patch does the following:
1. Created a new function, bgp_show_failed_summary to display the
failed summary output for JSON and vty
2. Created a new function to display the reset code/subcode. This is now used in the
failed summary code and in the show neighbors code
3. Added a new variable failedPeers in all the JSON outputs, including the vanilla
"show bgp summary" family. This lists the failed session count.
4. Display peer, dropped count, estd count, uptime and the reason for failure as the
output of "show bgp summary failed" family of commands
5. Added three resset codes for the case where we're waiting for NHT, waiting for peer
IPv6 addr, waiting for VRF to init.
This also counts the case where only one peer has advertised an AFI/SAFI.
The new command has the optional keyword "failed" added to the classical summary command.
The changes affect only one existing output, that of "show [ip] bgp neighbors <nbr>". As
we track the lack of NHT resolution for a peer or the lack of knowing a peer IPv6 addr,
the output of that command will show a "waiting for NHT" etc. as the last reset reason.
This patch includes update to the documentation too.

Problem reported that "clear bgp *" only cleared ipv6 peers.
Changed the logic to clear all afi/safis of all peers in
that case. Also improved the operation of clearing
individual afi/safi using soft/in/out to do the right thing.

This code doees this:
a) Imagine ospf installs a route into zebra. Zebra crashes and
we restart FRR. If we are using the -k option on zebra than
all routes are re-read in, including this OSPF route.
b) Now imagine at the same time that zebra is starting backup
ospf on a different router looses a link to the this route.
c) Since zebra was run with -k this OSPF route is read back
in but never replaced and we now have a route pointing out
an interface to other routers that cannot handle it.
We should never allow users to implement bad options from zebra's
perspective that allow them to put themselves into a clear problem
state and additionally we have *absolutely* no mechanism to ever
fix that broken route without special human interaction.

This plugin leverages the northbound API to integrate FRR with Sysrepo,
a YANG-based configuration and operational state data store.
The plugin is linked to the libsysrepo library and communicates with
the sysrepod daemon using GPB (Google Protocol Buffers) over AF_UNIX
sockets. The integration consists mostly of glue code that calls the
appropriate FRR northbound callbacks in response to events triggered
by the sysrepod daemon (e.g. request to change the configuration or to
fetch operational data).
To build the sysrepo plugin, provide the --enable-sysrepo option to the
configure script while building FRR (the libsysrepo library needs to be
installed in the system).
When installed, the sysrepo plugin will be available for all FRR daemons
and can be loaded using the -M (or --module) command line option.
Example: bgpd -M sysrepo.

This plugin leverages the northbound API to integrate FRR with the ConfD
management agent.
The plugin is linked to the libconfd library and communicates with the
confd daemon using local TCP sockets. The integration consists mostly
of glue code that calls the appropriate FRR northbound callbacks in
response to events triggered by the confd daemon (e.g. request to change
the configuration or to fetch operational data).
By integrating FRR with the libconfd library, FRR can be managed using
all northbound interfaces provided by ConfD, including NETCONF, RESTCONF
and their Web API.
The ConfD CDB API is used to handle configuration changes and the ConfD
Data Provider API is used to provide operational data, process RPCs and
send notifications. Support for configuration management using the ConfD
Data Provider API is not available at this point.
The ConfD optional 'get_object()' and 'get_next_object()' callbacks were
implemented for optimal performance when fetching operational data.
This plugins requires ConfD 6.5 or later since it uses the new leaf-list
API introduced in ConfD 6.5.
To install the plugin, the --enable-confd option should be given to the
configure script, specifying the location where ConfD is installed.
Example: ./configure --enable-confd=/root/confd-6.6
When installed, the confd plugin will be available for all FRR daemons
and can be loaded using the -M (or --module) command line option.
Example: zebra -M confd.
