Subject: [CCAMP] Problem of hostname display of each RSVP Hop

Hi, all:

Hostname display for OSPF and RSVP-TE can improve the operating 
experience. But when initiating an inter-area LSP tunnel with RSVP-TE, and 
tried to get the hostname of each RSVP Hop display on the CLI at the 
ingress node, it is impossible to obtain the hostname information of those 
nodes in areas other than the initiator's. 
The hostname flooding scope is controlled by the OSPF Opaque LSA, as 
described in [RFC5642]. That means the hostname information of a router 
other than an ASBR, cannot traverse OSPF routing areas.
The draft makes some extensions, please review and comment...

> Abstract:
> RFC 5642 defines an OSPF Router Information TLV that allows OSPF
> Routers to flood their hostname-to-Router-ID mapping information.
> Sometimes, when the operators create an inter-area MPLS LSP tunnel
> with Resource ReSerVation Protocol-Traffic Engineering (RSVP-TE),
> they need the hostname display on the CLI at the ingress node for
> management and operational reasons.  This document describes
> extensions to RSVP-TE to support hostname-to-Router-ID mapping
> information traversing areas in an inter-area MPLS LSP tunnel
> situation.
