    Hi All,

    The *rough* consensus here is to make the Instance field all 24 bits
    of the Opaque ID. The new wording is:

    2.2. LSA ID

       The LSA ID of an Opaque LSA is defined as having eight bits of type
       and 24 bits of type-specific data. The Traffic Engineering LSA uses
       type 1. The remaining 24 bits are the Instance field, as follows:

          0 1 2 3
          0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
         +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
         | 1 | Instance |
         +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

       The Instance field is an arbitrary value used to maintain multiple
       Traffic Engineering LSAs. A maximum of 16777216 Traffic Engineering
       LSAs may be sourced by a single system. The LSA ID has no
       topological significance.

    Also, I will add the following (similar to the ISIS TE doc) to 2.4.1:

       If a router advertises BGP routes with the BGP next hop attribute
       set to the BGP router ID, then the Router Address SHOULD be the same as
       the BGP router ID.

    Any other comments before I send this doc to John & Bill/Alex for IETF
    Last Call?

    Kireeti.
