Technical Summary
Use of Node-ID based RSVP Hello messages is implied in a number of
cases, e.g., when data and control plan are separated, when TE links
are unnumbered. Furthermore, when link level failure detection is
performed by some means other than exchanging RSVP Hello messages,
use of Node-ID based Hello session is optimal for detecting signaling
adjacency failure for Resource reSerVation Protocol-Traffic
Engineering (RSVP-TE). Nonetheless, this implied behavior is unclear
and this document formalizes use of Node-ID based RSVP Hello session
as a best current practice (BCP) in some scenarios. The procedure
described in this document applies to both Multi-Protocol Label
Switching (MPLS) and Generalized MPLS (GMPLS) capable nodes.
