## Configuration File Format 

 NLSR is configured using an [INFO file](http://www.boost.org/doc/libs/1_42_0/doc/html/boost_propertytree/parsers.html#boost_propertytree.parsers.info_parser). 

 ## Example configuration 

     ; the general section contains all the general settings for router 

     general 
     { 
     ; mandatory configuration command section network, site and router 
    
         network /ndn           ; name of the network the router belongs to in ndn URI format 
         site /memphis.edu      ; name of the site the router belongs to in ndn URI format 
         router /cs/pollux      ; name of the network the router belongs to in ndn URI format 

     ; lsa-refresh-time is the time in seconds, after which router will refresh its LSAs 
    
         lsa-refresh-time 1800        ; default value 1800. Valid values 240-7200 

     ; log-level is to set the levels of log for NLSR 

         log-level    INFO              ; default value INFO, valid value DEBUG, INFO 
     } 

     ; the neighbors section contains the configuration for router's neighbors and hello's behavior 

     neighbors 
     { 
     ; in case hello interest timed out, router will try 'hello-retries' times at 'hello-time-out'  
     ; seconds interval before giving up for any neighbors (deciding link is down)      

        hello-retries 3                       ; interest retries number in integer. Default value 3 
                                            ; valid values 1-10 

        hello-timeout 1                      ; interest time out value for hello interest. Default 
                                            ; value 1, Valid values 1-15 

        hello-interval    60                    ; hello interest sending interval in seconds. Default value 60 
                                            ; valid values 30-90 
     ; neighbor command is used to configure router's neighbor. Each neighbor will need 
     ; one block of neighbor command 
    
        neighbor 
        { 
            name /ndn/memphis.edu/cs/castor          ; name prefix of the neighbor router consists 
                                                   ; of network, site-name and router-name 
           
            face-uri    udp://castor.cs.memphis.edu    ; face Uri of the face connected to the neighbor 
            link-cost 20.6                           ; cost of the connecting link to neighbor 
        } 
     } 

     ; the hyperbolic section contains the configuration settings of enabling a router to calculate 
     ; routing table using [hyperbolic routing table calculation](http://arxiv.org/abs/0805.1266) method 

     hyperbolic 
     { 
     ; commands in this section follows a strict order 
     ; the switch is used to set hyperbolic routing calculation in NLSR 

         state off                ; default value 'off', set value 'on' to enable hyperbolic routing table  
                                ; calculation which turns link state routing 'off'. set value to 'dry-run" 
                                ; to test hyperbolic routing and compare with link state routing. 
     

         radius     123.456         ; radius of the router in hyperbolic coordinate system 
         angle      1.45            ; angle of the router in hyperbolic coordinate system 
     } 


     ; the fib section is used to configure parameters related fib entry's type to ndn FIB computation updated by NLSR 

     fib 
     { 
     ; the max-faces-per-prefix is used to limit the number of faces for each name prefix prefixes 
     ; by NLSR in ndn FIB 
    
         max-faces-per-prefix 3     ; default value 0. Valid value 0-60. By default (value 0) NLSR adds 
                                  ; all available faces for each reachable name prefixes in NDN FIB 
     
     } 

     ; the advertising section contains the configuration settings of the name prefixes  
     ; hosted by this router 

     advertising 
     { 
     ; the prefix is owned by used to advertised name from the router or directly reachable by the router. To advertise name prefixes, prefixes 
     ; configure one block of prefix configuration command for every name 
    
         prefix /ndn/edu/memphis/cs/netlab             ; name in ndn URI format 
         prefix /ndn/edu/memphis/sports/basketball  
     }
