Hi Olivier, Great news Olivier! I’m hoping you are looking at OSPFv3 Extended LSAs and OSPFv3 SR as well.
Thanks, Acee From: OSPF <ospf-boun...@ietf.org> on behalf of Olivier Dugeon <olivier.dug...@orange.com> Date: Tuesday, February 6, 2018 at 3:13 PM To: SPRING WG List <spr...@ietf.org>, OSPF WG List <ospf@ietf.org> Subject: [OSPF] Experimental support of OSPFv2 Segment Routing in Free Range Routing Hi all, We are please to announce that we have added Experimental support of OSPF SR (draft-ietf-ospf-segment-routing-extensions-24) in Free Range Routing protocol suite https://frrouting.org This feature is available on the master branch: https://github.com/FRRouting/frr and will be part of the future 4.0 release. Supported Features: * Automatic computation of Primary and Backup Adjacency SID with Cisco experimental remote IP address * SRGB configuration * Prefix configuration for Node SID with optional NO-PHP flag (Linux kernel support both mode) * Node MSD configuration (with Linux Kernel >= 4.10 a maximum of 32 labels could be stack) * Automatic provisioning of MPLS table * Static route configuration with label stack up to 32 labels Interoperability: * tested on various topology including point-to-point and LAN interfaces in a mix of Free Range Routing instance and Cisco IOS-XR 6.0.x * check OSPF LSA conformity with latest wireshark release 2.5.0-rc Known limitations * Runs only within default VRF * Only single Area is supported. ABR is not yet supported * Only SPF algorithm is supported * Extended Prefix Range is not supported * MPLS table are not flush at startup. Thus, restarting zebra process is mandatory to remove old MPLS entries in the data plane after a crash of ospfd daemon * With NO Penultimate Hop Popping, it is not possible to express a Segment Path with an Adjacency SID due to the impossibility for the Linux Kernel to perform double POP instruction. For details implementation & instructions on how to use this new feature, please consult doc/OSPF-SR.rst. Regards FRR team
