Re: [RRG] anycast/default as a transition tool [On the Transitionability of LISP]

Both anycast and default route also have similar failure modes, i.e.,
if a default/anycast route is advertised by a router which doesn't
have full topology information (or at least a lead where to forward
the packets to get it), connectivity of Internet is going to be
balkanized depending on which anycast/default you happen to be using.
Maybe we don't need a solution at the edges, just more default routing
Ultimately in the case of LISP all that is being offered is a mapping.
And so any ITR that advertises a default or supernet for
non-participants merely needs to have the entire mapping and offer to
map for those mappings.
