Excellent Article.

 

Is it possible to know which editing tool you have used to draw such a beautiful detailed explanaions with respect to protocol ?

Chris Yoo 2019-07-24 08:23:49

We mainly use Microsoft Visio as a drawing tool.

How does the the relay agent know the DHCP server IP and MAC?

chris 2019-10-15 11:35:32

The DHCP server IP should be configured on relay agent,

but MAC address of the DHCP server does not need to be known by the relay agent.

said 2020-05-22 11:01:57

The source port and destination port used between router and DHCP server must be 67 in both direction.

Vidhun 2020-06-18 15:42:15

Nice work, this gives a good explanation. 

Akhil 2020-06-30 03:16:37

Very informative article !! A quick note though, I think the source port from the relay agent should be 67 itself otherthan 68 whent the relay agent unicasts the packets to the Server. Correct me if i am wrong.

Very useful article on DHCP relay agent 

spidy_trench 2020-07-17 16:12:56

I've been surfing internet to get packet level explaination specifially with DHCP Server located on a different network, this is the best explaination I have ever came across.

 

- Great Job.  I can imagine your efforts and time behind this.
