Title   : BGP based Multi-homing in Virtual Private LAN Service

Abstract:
   Virtual Private LAN Service (VPLS) is a Layer 2 Virtual Private
   Network (VPN) that gives its customers the appearance that their
   sites are connected via a Local Area Network (LAN).  It is often
   required for the Service Provider (SP) to give the customer redundant
   connectivity to some sites, often called "multi-homing".  This memo
   shows how BGP-based multi-homing can be offered in the context of LDP
   and BGP VPLS solutions.  This document updates RFC 4761 by defining
   new flags in the Control Flags field of the Layer2 Info Extended
   Community.

2019-07-26 Thread Rabadan, Jorge (Nokia - US/Mountain View)
We just updated this draft with the security considerations.
As discussed by the WG chairs this week, it's ready for WG adoption call.

Comments are welcome.

Thanks.
Jorge

Abstract:
   Provider Backbone Bridging (PBB) can be combined with Ethernet VPN
   (EVPN) to deploy ELAN services in very large MPLS networks (PBB-
   EVPN). Single-Active Multi-homing and per-ISID Load-Balancing can be
   provided to access devices and aggregation networks. In order to
   speed up the network convergence in case of failures on Single-Active
   Multi-Homed Ethernet Segments, PBB-EVPN defines a CMAC-Flush
   mechanism that works for different Ethernet Segment BMAC address
   allocation models. This document complements those CMAC-Flush
   procedures for cases in which no PBB-EVPN Ethernet Segments are
   defined (ESI 0) and an ISID-based CMAC-Flush granularity is desired.

[bess] Comment at the mic

2019-07-26 Thread Robert Raszuk
Hey Keyur,

I would like to share my perspective on your comment made at the BESS
yesterday.

What you pointed out that VPN demux should be removed or renewed when we
rewrite bgp next hop is very true in 4364 world or even in EVPN world where
VPN label is of local significance.

But in Srihari's proposal VPN demux may be of domain wide significance
hence mandating its removal at each EBGP boundary in the spec would be a
bad hint.

See with SID indicating to which VRF packet belongs applied consistently by
say NMS your option C becomes seamless without any "next-hop-unchanged"
hacks nor making PE-PE for multihomed sites failover requires any fancy
shadow LFIBs or control plane "taps" into updates which just pass by.

So while in general my personal opinion is that we do not need yet one more
way of  protocol encoding to accomplish L3VPNs which already is shipping in
the form of 4364 and EVPN standards if WG decides to proceed let's learn
from the past experience here.

Cheers,
R.
