Abstract
This document describes a method for distributing an NHRP service
within a LIS [1]. This method uses the Server Cache Synchronization
Protocol (SCSP) [2] to synchronize the client information databases
held by NHRP Servers (NHSs) within a LIS.
1. Introduction
The keywords MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD,
SHOULD NOT, RECOMMENDED, MAY, and OPTIONAL, when they appear in this
document, are to be interpreted as described in [4].
NHRP Clients (NHCs) register their existence and reachability
information with NHRP Servers (NHSs). There may be multiple NHSs in
a given Logical IP Subnet (LIS). NHCs do not necessarily register
with all NHSs in a LIS; however, all NHCs need to be able to query at
least one NHS about any NHC within the LIS. Thus, the contents of
the NHS databases in a LIS need to be synchronized across the LIS.
The Server Cache Synchronization Protocol (SCSP) solves the
generalized server synchronization/cache-replication problem for
distributed databases and thus SCSP may be applied to the NHS
database synchronization problem within the LIS.
