could you modify the name of the Router at the end of the first page ?
When you are talking about the router 2, please write router R2 and not R1 as in your example.

By reading DD, the receiving router can determine what it is missing and them ask the sender to transmit required LSAs..

them should be then :)

rehan — Mon, 20 Oct 2014 14:00:54 +0000

Note: DD works like table fo content.

To 9tut: New OSPF question about the process of building the adjacency.You must provide the good stage position between Exstart, Exchange, Loading and Full. You have to put these steps in the right postion.

Hi,
Seems that there is typing mistake in here :

…using the following sequence:
+ The highest IP address assigned to a loopback (logical) interface.
+ If a loopback interface is not defined, the highest IP address of all active router’s physical interfaces will be chosen.
+ The router ID can be manually assigned

In fact the sequence is :
1- Manually assigned RID using #router-id A.B.C.D (router command)(even if A.B.C.D is not one of our interfaces’ IP)
2- Highest IP of assigned Loopback
3- Highest IP of active interfaces (up/up – up/down – but not down/down)

“Suppose OSPF has just been enabled on R1 & R2. Both R1 and R2 are very eager to discover if they have any neighbors nearby but before sending Hello messages they must first choose an OSPF router identifier (router-id) to tell their neighbors who they are. The Router ID (RID) is an IP address used to identify the router and is chosen using the following sequence:”
The router ID is a 32 bit number. It appears in the same quad dotted decimal format as an IP address, but it is not. If the router does not have a router ID specified, then the OSPF will chose the IP address on the first interface that comes up and use that as the RID.

the configuratuion is easy

in configuration mode

router # interface loopback 55

router # ip add “ip of network” ” subnet mask of network”

just lke this

55 can replace by any number

note: always loop back interface is up .

By: M7

M7 — Mon, 20 May 2013 11:29:38 +0000

hii
@ alper
What does loopback do ?

the most benefits of loop back interface it is always turn on ” because is logic interface ”

so I use loop back interface always to identify the router to make ” telent ,ping —etc”
