RE: Helper address usage

Chris,

You only need it on the local LAN interface where your DHCP client
resides.

Subject: Helper address usage

Group,

I have a question on the proper usage of the helper address, and I can
not
lab this up to test. I have a DHCP server that is down stream from the
request by a few broadcast domains. Below is my network

DHCP Client
|-------F0/0-R1-F0/1-----------|-----------F0/0-R4-F0/1--------------|--
----------------F0/0-R3-F0/1--------------------|
DHCP Server 100.1.3.99

 So my thinking is put the helper address on F0/0 of R1 with address
100.1.3.99, Do I also need to enable it on R4 and R3? and if so, on both
interfaces?

Any ideas?

Thanks
Chris
