  site /edu/memphis    ; name of the site the router belongs to in ndn URI format
  router /%C1.Router/cs/pollux    ; name of the router 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

  ; router-dead-interval is the time in seconds after which an inactive routers
  ; LSAs are removed
  ;router-dead-interval 3600 ; default value: 2*lsa-refresh-time. Value must be larger
                             ; than lsa-refresh-time

  ; InterestLifetime (in seconds) for LSA fetching
  lsa-interest-lifetime 4    ; default value 4. Valid values 1-60

  ; sync interest lifetime of ChronoSync in milliseconds
  sync-interest-lifetime 60000  ; default value 60000. Valid values 1000-120,000

  seq-dir       /var/lib/nlsr        ; path for sequence directory (Absolute path)
}

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

neighbors
{
  ; in case hello interest timed out, router will try 'hello-retries' times at 'hello-timeout'
  ; 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 in integer. Default value 1
                                       ; Valid values 1-15

   hello-interval  60                  ; interest sending interval in seconds. Default value 60
                                       ; valid values 30-90

  ; adj-lsa-build-interval is the time to wait in seconds after an Adjacency LSA build is scheduled
  ; before actually building the Adjacency LSA

  adj-lsa-build-interval 5   ; default value 5. Valid values 0-5. It is recommended that
                             ; adj-lsa-build-interval have a lower value than routing-calc-interval

  ; first-hello-interval is the time to wait in seconds before sending the first Hello Interest

  first-hello-interval  10   ; Default value 10. Valid values 0-10

  face-dataset-fetch-tries 3 ; default is 3. Valid values 1-10. The FaceDataset is
                             ; gotten from NFD, and is needed to configure NLSR
                             ; correctly. It is recommended not to set this
                             ; variable too high, because it could cause
                             ; congestion for NFD.

  face-dataset-fetch-interval 3600 ; default is 3600. Valid values 1800-5400.
                                   ; This controls how often (in seconds) NLSR will attempt to
                                   ; fetch a FaceStatus dataset from NFD.

; 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.

; the fib section is used to configure fib entrys type to ndn FIB updated by NLSR

fib
{
  ; the max-faces-per-prefix is used to limit the number of faces for each name 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

  ; routing-calc-interval is the time to wait in seconds after a routing table calculation is
  ; scheduled before actually performing the routing table calculation

  routing-calc-interval 15   ; default value 15. Valid values 0-15. It is recommended that
                             ; routing-calc-interval have a higher value than adj-lsa-build-interval
}

; the advertising section contains the configuration settings of the name prefixes
