| Answer | HI Buddy.... Didn't get ur question.. Cud u explain
plzzz.... OG stands for...
Don't mind plzzzzz...  |

| Answer | If u r talking about need of command: ip helper-address, thn
i can say about it.
In CCNA studies, we got to know that router always block the
broadcast traffic, dats fine.
But if ur organization's network is establish in such a way:
client-------Router------- DNS Server
!
!
!
!
DHCP Server
Now... if ur pc want to locate DNS server thro broadcast,
broadcast traffic will come from client pc to all the way to
Router.
Wat router will do now, Router will block all the broadacast
traffic. As we learn in our previous studies. Ryt....
So client PC will unable to locate DNS server, coz router
doesn't allow to broadcast the traffic.
Same case, if Client PC want to gain IP address, it will
broadcast...n requesting for IP address from DHCP server.
I hope u knw the DHCP process, I mean "DORA" process. In
this case also router block all the broadcast traffic.
So wats the solution for this....
By configuring IP address on the interface subconfig mode..
with the help of (ip helper-address A.B.C.D)....
wat it'll do, The UDP broadcasts traffics are translated
into a unicast by the router, making the communication
possible.
The command should be configured on the interface that will
be receiving the broadcasts.
Router(config)#interface fastethernet 0/0
Router(config-if)#ip helper-address A.B.C.D
where A.B.C.D is the IP address of ur DNS/DHCP server.
One more point is there, this ip-helper address doesn't
forward all the UDP broadcast.. it broadcast only 8 UDP
services.. like..
1. TIME, port 37
2. TACACS, port 49
3. DNS, port 53
4. BOOTP/DHCP Server, port 67
5. BOOTP/DHCP Client, port 68
6. TFTP, port 69
7. NetBIOS name service, port 137
8. NetBIOS datagram service, port 138
if u want to include any more UDp services the command is
Router(config)#ip forward-protocol udp (port Number)
Hope this post helps u to understand the use of command n
circumstances of command when to use it n how to use it.
Looking forward ur feedback. If i did anymistake the let me
know plzzzzzzzzz...
Cheers.. hv a nice day buddy.  |

Why Authentication Header (AH) is not compatible with the

| Answer | AH is a protocol that provides authentication.
of either all or part of the contents of a datagram.
through the addition of a header that is calculated,
based on the values in the datagram.
What parts of the datagram are used for the calculation,
and the placement of the header, depends on the mode(tunnelor transport)and the version of IP (IPv4 or IPv6).
tunnel or transport-------
tunel
/\
/ \
/ \
tunel transport

protect all data pkt protect only data portion
now why it is not compatible with nat nat is mechanism.
to hide your personal ip sometime theoretically
it is a mechanism to convert private ip to public ip
___________________________________________________________
*******
The IPsec Authentication Header (AH) is a case in point. AH runs the entire IP packet, including invariant header fields like source and destination address, through a message digest algorithm to produce a keyed hash.
This hash is used by the recipient to authenticate the packet.
If any field in the original IP packet is modified, authentication will fail and the recipient will discard the packet. AH is intended to prevent unauthorized modification, source spoofing, and man-in-the-middle attacks. But NAT, by definition, \
modifies IP packets. Ergo, AH + NAT cannot work.
In the nat Ip filed is modified so some time Ah is not compatible with nat i am again saying SOME time.
Thanku
Hope this will help to understand you the concepts.
