Abstract:
There is a need to connect (a) TRILL based data centers or (b) TRILL
based networks which provide Provider Backbone like functionalities
or (c) Campus TRILL based networks over the WAN using one or more
ISPs that provide regular IP+GRE or IP+MPLS transport. Some of the
solutions proposed as in [DRAFT-EVPN] have not dealt with the
scalable methods in their details as to how these services could be
provided such that multiple TRILL sites can be inter-connected with
issues like nick-name collisions for unicast and multicast being
taken care of. It has been found that with extensions to BGP and a
scalable method on Provider edge devices the problem statement which
we will define below can be handled. Specifically the division of the
nick-name into site-id and Rbridge-ID is one that can limit the
number of sites that can be interconnected and the number of Rbridges
within each such site that can be provisioned. The draft proposed
herein deals / overcomes these issues by not limiting the number of
sites and Rbridges within a TRILL site interconnect. Only the maximum
space for a nick-name which happens to be 16 bits is the actual
limit. MAC moves across TRILL sites and within TRILL sites can also
be realized. This document / proposal envisions the use of BGP-MAC-
VPN vrfs at the ISP cloud PE devices. We deal in depth with the
control plane and data plane particulars for unicast and multicast in
this scheme. Additionally Provider Backbone like functionality is
also covered.
