hi,

here we go... the dataplane features i marked will be out soon for p4, and
mostly all are here in the dpdk code...



in dataplane only featuers:

RFC 8279 (was draft-ietf-bier-architecture) Multicast Using Bit Index
Explicit Replication (BIER)

RFC 8296 (was draft-ietf-bier-mpls-encapsulation) Encapsulation for Bit Index
Explicit Replication (BIER) in MPLS and Non-MPLS Networks



control plane only features:

RFC 8401 (was draft-ietf-bier-isis-extensions) Bit Index Explicit Replication
(BIER) Support via IS-IS

RFC 8444 (was draft-ietf-bier-ospf-bier-extensions) OSPFv2 Extensions for Bit
Index Explicit Replication (BIER)

draft-ietf-bier-pim-signaling-11 PIM Signaling Through BIER Core <--- also
have dataplane needs, which also available

draft-ietf-bier-evpn-04 EVPN BUM Using BIER <--- only available in software
forwarding at the moment!


regrads,
cs

Hi,

This all looks very encouraging!

Can we say anything about compliance with or which parts of the IETF bier RFC
and drafts the implementation supports?

(As per https://datatracker.ietf.org/wg/bier/documents/ which lists the 5
RFCs and the many drafts)

hi,
the bier core (phase 1, we can say:) feature just arrived to the p4emu (dpdk,
libpcap) dataplane....
i need to do some housekeeping around it like adding the test cases for it
and so on but i'm sure
that it works as i use it extensively on my homenet... back in time kifu
deployed a probe network
to test it's mpls core.. there was not such a software that suited our needs
so i added the missing
pieces to freertr so now it can do a so called 'mesh tracker'. it can operate
in unicast or multicast.
it does only 2 thing: periodically fetches the peer list, and sends reports
to the peers...
the output is pretty self-explanatiory (1) a connectivity matrix.. in my case
it all goes over
bier (2) according to the local mroute and mldp tables...
as every packet hold's the info where it wants to get itself replicated, the
uplink of the
tester knows nothing about the existence of the s,g groups (3).. this is what
we call stateless!
the only thing it knows is the bier bitmaps (4) computed by the igp in my
case...
as you can see, there were only hw switched packets, the freertr itselt did
not get involved
in the replication at all... hereby i would like to note that those hairpins
(5) are all
macsec-ed interfaces here as they're bridged toward the vpn tunnels to my
other sites...
for those who are skeptical about the mtracker thingy, you can spot in (1)
that some peers had
130 reports while others just 10, this is because on the first try the
flooding did not worked
on hairpins as you can see on the failed (6) mtracker output, only my
internal nodes had connectivity....
regards,
cs
