NLSR

## 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 router section contains the setting of network, site name 

    ; and router name which all together makes router-prefix

    router

    {

        network

        {

            name /ndn             ; name prefix of the network router belongs to

        }                         ; must be in ndn URI format

        site-name

        {

            name /memphis.edu     ; name prefix of the site name router belongs to

        }                         ; must be in ndn URI format

        router-name

        {

            name /cs/pollux       ; name prefix of the router

        }                         ; must be in ndn URI format

    }

    ; the hello section describes the configuration settings for NLSR hello protocol

    hello

    {

    ; 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

           host cs.castor.memphis.edu      ; hostname or ip address of neighbor router

           link-cost 20.6                  ; cost of the connecting link to neighbor

       }

    ; interest-retry command is used to configure the interval of hello interest and number

    ; of retry interests before a router gives up in case of interest timed out

       interest-retry

       {

           number    3      ; interest retry number in integer. Default value 3

                            ; valid values 1-10

           interval  10     ; interest sending interval in seconds. Default value 1

                            ; valid values 1-15

       }

    }

    ; the synchronization section contains all the configuration settings for router's update

    ; synchronization with neighbors in the network

    synchronization

    {

    ; all routers in the network must have same sync-prefix. Routers synchronizes routing updates

    ; in this prefix across the network. This prefix is routable to each neighbor from every router

        sync-prefix

        {

            name /ndn/nlsr/sync    ; name in URI format. Default value /ndn/nlsr/sync

        }

    ; lsa-refresh-time is the time in seconds, after which router will refresh its LSAs

        lsa-refresh-time

        {

            seconds 1800           ; default value 1800. Valid values 240-7200

        }

    }

    ; 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
