  ; 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

  ; select sync protocol: chronosync or psync
  sync-protocol psync

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

  state-dir       /var/lib/nlsr        ; path for intermediate state files including sequence directory (Absolute path)
}

; the neighbors section contains the configuration for router's neighbors and hello protocol 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 seconds. 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 10   ; default value 10. Valid values 5-30.

  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 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
