An issue just crept up and I hoping to post here for some clarification.
We have multiple vlans but only two are being effected.
vlan 26 - 10.10.26.x
vlan 27 - 10.10.27.x
both configured with ip helper-address 10.10.16.45
Nobody currently can recieve dhcp addresses on the 26 but if I turn off the helper address on the 26 vlan they recieve 10.10.27.x addresses.
If I turn the helper back on the 26 and turn it off on the 27, 27 users get a 26 address.
Would this be an issue on the 6500 or is this a problem with a possible rogue dhcp server? Or for that matter a problem with our DHCP server? (10.10.16.45 is the only authorized dhcp server on 2k3 box)
