Gaurav,
I don't know how the default client-id is created, but I use this method to
assign IPs to the clients:
On R1, R2
interface f0/0
ip address dhcp client-id f0/0 <<=== Set the Client-ID to mac address of
the interface.
Mac-address 0063.6973.636f
end
then R1 will use its f0/0 mac-address as client-id.
And you can configure R3 in this way:
ip dhcp pool TEST
host 172.16.12.2 255.255.0.0
client-identifier 0063.6973.636f

Subject: DHCP client-identifier
HI Group
I have following setup
R1====|
|
|==== R3
|
R2====
My DHCP server is running on R3 .
I want say 172.16.12.2 to be assigned to R1 and 172.16.12.12 to be
assigned to R2.
I am able to do this using host and client identifier .
R3(config)#do sh run | sec dhcp
ip dhcp pool TEST
host 172.16.12.2 255.255.0.0
client-identifier
0063.6973.636f.2d30.3031.632e.3538.6261.2e66.6532.302d.4661.302f.30
ip dhcp pool TEST1
host 172.16.12.12 255.255.0.0
client-identifier
0063.6973.636f.2d30.3031.612e.6132.6166.2e36.3830.382d.4661.302f.30
R3(config)#
My query is is there a way to CALCULATE the client identifier ?
I got the above by simply creating a DHCP pool on R3(server) in this
case to start off and enabling DHCP debugs .
As address is assigned by server to clients .. we do get what address
is assigned to what client
But is there a way we can somehow calculate this ?
Thnx
