14. OSPF

Time for some OSPF configs, these will build off the previous configs we just

did. For this lab, the other router, R2, was preconfigured to support the

connections.

We will place our loopback and out g0/3/0/2 interface into OSPF process LAB

and area 0.0.0.0

RP/0/7/CPU0:R1#

RP/0/7/CPU0:R1#conf t

Thu Mar 29 19:37:52.671 UTC

Define our OSPF process name

RP/0/7/CPU0:R1(config)#router ospf LAB

Now to define our area first

RP/0/7/CPU0:R1(config-ospf)#area 0.0.0.0

Now we can place the interfaces into the area, no need to entering subnets

RP/0/7/CPU0:R1(config-ospf-ar)#inter loo0

RP/0/7/CPU0:R1(config-ospf-ar-if)#inter g0/3/0/2

RP/0/7/CPU0:R1(config-ospf-ar-if)#exit

RP/0/7/CPU0:R1(config-ospf-ar)#exit

RP/0/7/CPU0:R1(config-ospf)#exit

RP/0/7/CPU0:R1(config)#commit

Thu Mar 29 19:38:15.182 UTC

RP/0/7/CPU0:R1(config)#

Now to look at our IP Protocols running:

RP/0/7/CPU0:R1#sh ip proto

Routing Protocol OSPF LAB

Router Id: 1.1.1.1

Distance: 110

Non-Stop Forwarding: Disabled

Redistribution:

None

Area 0.0.0.0

Loopback0

GigabitEthernet0/3/0/2

RP/0/7/CPU0:R1#

We can see what we have OSPF LAB running with a RouterID of 1.1.1.1 (our

loopback). It tells us what interfaces are in Area 0.0.0.0 as well.
