BGP Engines with support to "RTFilter address-family"
We are implementing an interesting L3VPN scenario for distributed DFZ on mid-size PEs. And we believe that the RT Constrained Route Distribution, RFC4684, will be ideal to solve the problems of operational levels for the intervention of configurations between PEs and Route-Reflectors. However, I'm searching for BGP Engines that implement this address-family (AFI=1, SAFI=132), to avoid Lock-In. In Cisco, this feature is covered, for example, in this document: https://www.cisco.com/c/en/us/support/docs/multiprotocol-label-switching-mpl... In Juniper, in that document: https://www.juniper.net/documentation/us/en/software/junos/vpn-l3/topics/top... IP Infusion's OCNOS also implements this functionality. I think Nokia implements it too. But I'm looking for an open-source engine that supports it. The official FRR documentation does not mention anything about RFC 4364, or RTFilter address family. So, I think FRR does not support RTFilter Constrained Route Distribution. Do any of the colleagues have any suggestions on this? -- Douglas Fernando Fischer Engº de Controle e Automação

FRR hasn’t implemented RFC4364 (nor planning to my knowledge (unless someone comes and codes it ;-)) I believe - Arccus has implemented it (Keyur to confirm). Cheers, Jeff

Confirming the implementation support on ArcOS (from Arrcus). :) Best Regards, Keyur

rustybgp and gobgp might support it. $ grep -r -P "AFI,SAFI = 1,132" rustybgp gobgp rustybgp/tools/pyang_plugins/gobgp.yang: "Route target membership (AFI,SAFI = 1,132)"; gobgp/tools/pyang_plugins/gobgp.yang: "Route target membership (AFI,SAFI = 1,132)"; Nothing on FRR $ grep -P -r -i 'IANA_SAFI_.* = 1\d{2,}' frr frr/lib/iana_afi.h: IANA_SAFI_MPLS_VPN = 128, frr/lib/iana_afi.h: IANA_SAFI_FLOWSPEC = 133 The mentions in the FRR issue tracker are (now) old entries.
