Add an API that allows IGP client daemons to register/unregister RLFAs with ldpd. IGP daemons need to be able to query the LDP labels needed by RLFAs and monitor label updates that might affect those RLFAs. This is similar to the NHT mechanism used by bgpd to resolve and monitor recursive nexthops. This API is based on the following ZAPI opaque messages: * LDP_RLFA_REGISTER: used by IGP daemons to register an RLFA with ldpd. * LDP_RLFA_UNREGISTER_ALL: used by IGP daemons to unregister all of their RLFAs with ldpd. * LDP_RLFA_LABELS: used by ldpd to send RLFA labels to the registered clients. For each RLFA, ldpd needs to return the following labels: * Outer label(s): the labels advertised by the adjacent routers to reach the PQ node; * Inner label: the label advertised by the PQ node to reach the RLFA destination. For the inner label, ldpd automatically establishes a targeted neighborship with the PQ node if one doesn't already exist. For that to work, the PQ node needs to be configured to accept targeted hello messages. If that doesn't happen, ldpd doesn't send a response to the IGP client daemon which in turn won't be able to activate the previously computed RLFA.

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.
