Subject: Re: [c-nsp] UDP-helper problem
Yes there is a route to a.b.c.d and yes we can ping the DHCP server
from everywhere, including the new sup.

I have recently moved the routing of a subnet from an old sup2/msfc2

msfc3 6500 (Version 12.2(18)SXF13, RELEASE SOFTWARE (fc1)). On the
old
router the udp-helper command worked fine, but on the new router I
can
see the DHCP address coming in but not the reply coming back and the
DHCP server isn't seeing the request arriving. Can anyone suggest
why
this might have stopped working (it isn't an ACL or firewall issue
as
there aren't any in the way) and I haven't turned _off_ any
component
of udp-helper (i.e. using the ip forward-protocol command).
interface Vlan937
description XXXYYYZZZ
ip address w.x.y.z 255.255.255.192
ip helper-address a.b.c.d
From this new sup, do you have a route to a.b.c.d? Can you ping the
DHCP server from this new sup?
