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.

FRRouting
FRR is free software that implements and manages various IPv4 and IPv6 routing protocols. It runs on nearly all distributions of Linux and BSD and supports all modern CPU architectures.
FRR currently supports the following protocols:
- BGP
- OSPFv2
- OSPFv3
- RIPv1
- RIPv2
- RIPng
- IS-IS
- PIM-SM/MSDP
- LDP
- BFD
- Babel
- PBR
- OpenFabric
- VRRP
- EIGRP (alpha)
- NHRP (alpha)
Installation & Use
For source tarballs, see the releases page.
For Debian and its derivatives, use the APT repository at https://deb.frrouting.org/.
Instructions on building and installing from source for supported platforms may be found in the developer docs.
Once installed, please refer to the user guide for instructions on use.
