6.11.14 Configure the OSPF Administrative Distances
An administrative distance is a rating of the trustworthiness of a routing information source, such as an
individual router or a group of routers. Numerically, an administrative distance is an integer between 0
and 255. In general, the higher the value is, the lower the trust rating is. An administrative distance of
255 means the routing information source cannot be trusted at all and should be ignored.
OSPF uses three different administrative distances: intra-area, inter-area, and external. Routes within
an area are intra-area; routes to another area are inter-area; and routes from another routing domain
learned via redistribution are external. The default distance for each type of route is 110.
To change any of the OSPF distance values, use the following command in router configuration mode:
distance ospf [intra-area dist1]
[inter-area dist2] [external dist3]
In the prompt select 6 option ，prompt is as below:
(00)<1-255>
(01)ospf OSPF distance
Please Input the code of command to be excute(0-1): 1
input 1，Select ospf option ，prompt is as below:
(00)external
(01)inter-area
(02)intra-area
Please Input the code of command to be excute(0-2): 0
Select parameter and specify the administrative distance value .

6.11.15 Configure Route Calculation Timers

You can configure the delay time between when OSPF receives a topology change and when it starts a
shortest path first (SPF) calculation. You can also configure the hold time between two consecutive
SPF calculations. To do this, use the following command in router configuration mode:
timers delay delaytime
timers hold holdtime
promptselect 21 option ，prompt is as below:
(00)delay
(01)hold
Please Input the code of command to be excute(0-1): 0
Select 0，then specify the time delay for route calculating.
Select 1，then configure the minimum interval of route calculating.
6.11.16 Monitor and Maintain OSPF
You can display specific statistics such as the contents of IP routing tables, caches, and databases.
Information provided can be used to determine resource utilization and solve network problems. You
can also display information about node reachability and discover the routing path your device's
packets are taking through the network.
