RFC 2457                Extended Border Node MIB           November 1998


3.1.4 ebnCos group

   The ebnCos group contains the ebnCosMapTable, which specifies how COS
   values are mapped between the non-native subnetwork and the native
   subnetwork.

3.1.5  ebnSubnetRoutingList group

   The ebnSubnetRoutingList group contains information about the
   customer-supplied EBN subnetwork routing list, which indicates to
   which adjacent nodes an EBN will forward LOCATE search requests. It
   consists of the following tables:

   1.  ebnSubnetSearchTable

       This table has an entry for each LU name that has a defined
       subnet routing list.  The LU name may identify a single LU, or it
       may contain a wildcard character that could identify a group of
       LUs (partial wildcard) or all LUs (full wildcard).  The objects
       in the table indicate whether the EBN may add dynamic entries to
       the subnet routing list, and whether the subnet routing list
       entries may be reordered for better search performance.

   2.  ebnSearchTable

       This table has an entry for each control point name which is
       included in a multi-subnet search for a particular LU name.  The
       index to the table is the LU name to be searched for, and an
       index which lists the order in which the CP names are to be
       searched.  Both the CP name and the LU name entries in the table
       allow for partial and full wildcards.  The CP name also allows
       for  special entries that indicate that the EBN will search
       itself and its own native subnetwork at this point in the search,
       or will search all native EBNs.

3.1.6 hbn group

   The hbn group contains information about HBN (HPR EBN) intermediate
   sessions.  The hbnIsInTable is an extension to the appnIsInTable.
   This table is present for intermediate sessions when there are back-
   to-back RTP (Rapid Transport Protocol) connections in an HBN.  It
   provides the NCE ID (network connection endpoint identifier) and TCID
   (transport connection identifier) for the second RTP connection.
