Implemented as per the feature description given in the source link.
Descriprion:
The BGP conditional advertisement feature uses the non-exist-map or exist-map
and the advertise-map keywords of the neighbor advertise-map command in order
to track routes by the route prefix.
non-exist-map :
If a route prefix is not present in output of the non-exist-map command, then
the route specified by the advertise-map command is announced.
exist-map :
If a route prefix is present in output of the exist-map command, then the route
specified by the advertise-map command is announced.
The conditional BGP announcements are sent in addition to the normal
announcements that a BGP router sends to its peers.
The conditional advertisement process is triggered by the BGP scanner process,
which runs every 60 seconds. This means that the maximum time for the conditional
advertisement to take effect is 60 seconds. The conditional advertisement can take
effect sooner, depending on when the tracked route is removed from the BGP table
and when the next instance of the BGP scanner occurs.

Add the "n-flag-clear" option to the "segment-routing prefix"
command. The only thing that option does is to clear the node
flag of the Prefix-SID, even if it corresponds to a local loopback
address. No changes are necessary other than that in order to fully
support Anycast-SIDs. isisd already supports multiple routers
advertising the same route with the same Prefix-SID after the recent
refactoring. Clearing the node flag for such anycast routes isn't
strictly required, but failure to do so can lead to problems like
TI-LFA picking the wrong Prefix-SID when calculating repair paths.
Signed-off-by: Renato Westphal <renato@opensourcerouting.org>
Embed Prefix-SID information inside SPF data structures so that
Prefix-SIDs can be installed together with their associated routes
at the end of the SPF algorithm. This is different from the current
implementation where Prefix-SIDs are parsed and processed separately,
which is vastly suboptimal.
Advantages of the new code:
* No need to parse the LSPDB an additional time to detect and process
SR-related changes;
* Routes are installed with their Prefix-SID labels in the same ZAPI
message. This can prevent packet dropping for a few milliseconds
after each SPF run if there are BGP-labeled routes (e.g. L3VPN) that
recurse on IGP labeled routes;
* Much easier to support Anycast-SIDs, as the SPF code will naturally
figure out the best nexthops and use only them (that can't be done
in any reasonable way if the Prefix-SID Sub-TVLs are processed
separately);
* Less code to maintain and reduced memory footprint;
The "show isis segment-routing prefix-sids" command was removed as
it doesn't make sense anymore now that "show isis route" exists.
Prefix-SIDs are a property of routes, so what was done was to extend
the "show isis route" command with a new "prefix-sid" option that
changes the output table to show the Prefix-SID information associated
to each route.

BFD profiles can now be used on the interface level like this:
interface eth1
ip router isis 1
isis bfd
isis bfd profile default
Here the 'default' profile needs to be specified as usual in the
bfdd configuration.
Signed-off-by: GalaxyGorilla <sascha@netdef.org>
The tests work with the default settings of BFD meaning that bfdd is
able to recognize a 'down' link after ~900ms so a route recovery should
be visible in the RIB after 1 second.
In the current state only IPv4 is used (when using IPv6
autoconfiguration) within BFD, even though the recovery also affects
IPv6 routes. This is different to the current state of ospfd/ospf6d in
combination with BFD since both IPv4 and IPv6 sessions are used there.
The following topology is used:
+---------+
| |
eth-rt2 (.1) | RT1 | eth-rt3 (.1)
+----------+ 1.1.1.1 +----------+
| | | |
| +---------+ |
| |
| 10.0.2.0/24 |
| |
| eth-rt1 | (.2)
| 10.0.1.0/24 +----+----+
| | |
| | RT3 |
| | 3.3.3.3 |
| | |
(.2) | eth-rt1 +----+----+
+----+----+ eth-rt4 | (.1)
| | |
| RT2 | |
| 2.2.2.2 | 10.0.4.0/24 |
| | |
+----+----+ |
(.1) | eth-rt5 eth-rt3 | (.2)
| +----+----+
| | |
| | RT4 |
| | 4.4.4.4 |
| | |
| +----+----+
| 10.0.3.0/24 eth-rt5 | (.1)
| |
| |
| 10.0.5.0/24 |
| |
| +---------+ |
| | | |
+----------+ RT5 +----------+
eth-rt2 (.2) | 5.5.5.5 | eth-rt4 (.2)
| |
+---------+
Route recovery is tested on RT1. The focus here lies on the two
different routes to RT5. Link failures are generated by taking
down interfaces via the mininet Python interface on RT2 and RT3.
Hence routes are supposed to be adjusted to use RT3 when a link
failure happens on RT2 or vice versa.
Note that only failure recognition and recovery is "fast". BFD
does not monitor a link becoming available again.

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.
