Subject: [mpls-tp] Query regarding use of NodeId in case of IP aware MPLS-TP network

Hello All,

Section 4 of the MPLS-TP identifiers draft-03 specifies:

   "Where IPv4 addresses are used, it is
   "convenient" to use the Node's IPv4 loopback address as the Node_ID,
   however the Node_ID does not need to have any association with the
   IPv4 address space used in the operator's IGP or BGP.  Where IPv6
   addresses are used exclusively, a domain unique 32- bit value is
   assigned"

When IP based addressing is used isnt it a "MUST" to use Node-Id as
an IPv4 address (sayIPv4 loopback address or router id).
>From the above text it looks that in such a case NodeId need not
mandatorily be an IPv4 address.

Thanks
Selvan
