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. A few
solutions have been proposed as in [1] in the recent past that have
not looked at the PB-like functionality. These solutions have not
dealt with the details as to how these services could be provided
such that multiple TRILL sites can be inter-connected with issues
like nick-name collisons for unicast (multicast is still TBD) being
taken care of. It has been found that with extensions to BGP the
problem statement which we will define below can be handled. Both
control plane and data plane operations can be driven into the
solution to make it seamlessly look at the entire set of TRILL sites
as a single entity which then can be viewed as one single Layer 2
cloud. MAC moves across TRILL sites and within TRILL sites can be
realized. This document / proposal envisions the use of BGP-MAC-VPN
vrfs both at the IP cloud PE devices and at the peripheral PEs within
a TRILL site providing Provider Backbone like functionality. We deal
in depth with the control plane and data plane particulars for
unicast (multicast is still TBD) with nick-name election being taken
care of as part of the solution.
