-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
