RA#debug ip ospf events

00:37:50: OSPF: Rcv pkt from 172.16.3.2, FastEthernet0/1, area 0.0.0.3

00:37:54 OSPF: Rcv hello from 192.168.2.1 area 0.0.0.1 from FastEthernet0/0 172.16.2.2 

I want to know the meaning of these outcome .

especially

00:37:54 OSPF: Rcv hello from 192.168.2.1 area 0.0.0.1 from FastEthernet0/0 172.16.2.2

RA received hello from 192.168.2.1 area 0 and what ??

also Is there any Documentation or URL which explain how to see all debug outcome ?

for example , debug ip rip , debug ip packet
debug ip ospf packet

etc... I really need to figure out the outcome of these debug command .

To display information on Open Shortest Path First  (OSPF)-related events, such as adjacencies, flooding information,  designated router selection, and shortest path first (SPF) calculation,  use the

thank you for reply and the link URL .

but I couldnt find what i want to know about this in the link .

00:37:54 OSPF: Rcv hello from 192.168.2.1 area 0.0.0.1 from FastEthernet0/0 172.16.2.2

In this output ,

Rcv hello from 192.168.2.1 area 0.0.0.1 →　means from neighbor 192.168.2.1 ( area 1) RA got the hello packet .

is this correct ?

if so ,

What does mean by " from FastEthernet0/0 172.16.2.2" ???

please help me out

Hi,

192.168.2.1 is the OSPF RID from the neighbour and the hello was received on Fastethernet0/0 and the IP address of the interface sending the hello is 172.16.2.2.

Regards.
