It seems that Cisco supports only facility backup method of fast-reroute 
extensions , with signalization
via setting bits in SESSION_ATTRIBUTE flag field. I have tested that tunnels 
brought up
by cisco with 12.0(30)S  as head-end with configured node-link protection 
are working well with juniper boxes - where tology allows
bypass tunnels are pressignalled by junipers protecting from link/node 
failure.
Cisco head-end are configured with "tunnel mpls traffic-eng fast-reroute 
node-protect" and
juniper routers with "set protocols rsvp interface x link-protection" where 
appropriate.
Additionally , Juniper also supports one-to-one protection method , with 
FAST_REROUTE and
DETOUR objects used for signalization.Needless to say , Cisco doesn't 
understand those objects and therefore
can't act as PLR or merge point for detour lsp's ( since Juniper uses backup 
path identification method by including DETOUR
object ) . Question is if you need one-to-one protection scheme...
