Hi Claus and all,

Somewhat related to this topic, we are preparing 
a draft (see in attachment), but it is not submitted 
yet. Please feel free to comment it.

This draft proposes a Backup Explicit Route Object (BERO) 
such that the ingress router can give the path of the 
backup LSPs. In addition, a Backup Record Route Object (BRRO) 
is defined such that the ingress router sees the paths 
of all backup LSPs in order to check if they complies 
with the BERO be-cause we defined the BERO as an advisory 
object.

Any feedback would be highly appreciated.

Many thanks,

Stefaan
