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.

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.
