+NLSR0.0
+=======
+
+Named-data Link State Routing ( NLSR ):
+  NLSR is routing protocol caluclate routing table dynamically and manipulate 
+ccnd forwarding information base (FIB) based on routing table.
+
+1. Download:
+	Check out the code from the github by following
+git://github.com/NDN-Routing/NLSR0.0.git
+
+2. Installation:
+	For installation of NLSR you must need to have ccnd installed. Go to NLSR0.0.
+Then make it and install by following
+
+$make
+$sudo make install
+
+3. Configuring NLSR:
+	For the explanation of configuring NLSR, we will consider following network topology.
+

+
+3.1 Creating faces for neighbors
+	For configuring of NLSR first system admin first need to create faces for the neighbors.
+For router having router-name /ndn/memphis.edu/castor, system admin need to create two faces for
+neighbors routers /ndn/memphis.edu/pollux and /ndn/memphis.edu/mira. By ccndc utility one can
+create face as below
+
+$ccndc add /ndn/memphis.edu/pollux udp pollux.cs.memphis.edu
+$ccndc add /ndn/memphis.edu/mira udp mira.cs.memphis.edu
+
+Let us assume that that face id for /ndn/memphis.edu/pollux is 9 and /ndn/memphis.edu/mira is 11.
+
+3.2 Configuration Commands
+3.2.1 router-name /name/prefix/of/router
+	router-name commands assigns name of the router. Router-name is unique in the network and
+maintained by name management. This is mandatory configuration command.
+
+3.2.2 ccnneighbor /name/prefix/of/neighbor/router faceX.
+	By this command router configures neighboring router. X is integer and must be precedeed 
+by "face". faceX is the connecting face for that neighbors.
+
+3.2.3 ccnname /name/prefix/to/be/advertised
+	With this configuration command router advertise name prefix
+
+3.2.4 lsdb-synch-interval secs
+	its the time interval after which neighbors will synchronize Link State Database. Default
+value is 300.
+
+3.2.5 interest-retry tries
+	its number of tries router will try if interest is timed out. Defualt value is 3.
+
+3.2.6 interest-resend-time secs
+	its the amount of time after which interest for a content will timed out. Defualt value
+is 15.
+
+3.2.7 lsa-refresh-time secs
+	its the amount of time after which router will regenerate its own LSDB and regenerate
+every LSA. Default value is 1800.
+
+3.2.8 router-dead-interval secs
+	its the amounnt of time after which a router will consider its neighbor dead if it does
+not hear anything from the neighbor. Default value 3600.
+
+3.2.9 multi-path-face-num n
+	with this command one activate to do multi-path routing. If n is greater than 1 then
+multi-path is triggered on and n faces will be added in ccnd fib after routing table calculation.
+Default value is 0 and then NLSR perform single path routing.
+
+3.2.10 logdir path/to/log/dir
+	By this command one can configure where NLSR will write logfiles. By default NLSR will
+write log file to /home/nlsrLog/ directory.
+
+3.3 Sample configuration file
+	Let assume that router /ndn/memphis.edu/castor wants to advertise two names 
+/ndn/memphis.edu/cslab/netlab and /ndn/memphis.edu/cslab/wisemanet. Configuration file for 
+/ndn/memphis.edu/castor will look like below 
+
+!-----Configuration file starts here
+
+router-name /ndn/memphis.edu/castor
