I have reviewed draft-ietf-pim-mofrr-tilfa-05.txt. I am not deep into
multicast routing and hence I look at the document from a general
operational perspective.

I found the document to be well written, the example topology to
outline the limitations of existing approaches is much appreciated.

How is this extension deployed? Can it be deployed incrementally or do
all multicast routers have to understand the RPF Vector Attributes in
the PIM Join packet to work properly? And are there any further
recommendations	about debugging	operational or deployment errors, are
there procedures to verify that the calculated alternative routes or
is this	no different than with other fast multicast reroute
mechanisms?
