Hi All,

       Yes,as Eric said,Label space implementations can be implementation specific.

       Regards,

       Abhay.

         This is correct. Within the context of the mpls-te-mib,
when configuring te tunnels it is not important to know where
the labels are coming from to signal the tunnels. This
information is provided by the LSR/LDP MIBs.
