Hi Martin,
We are migrating from Lucent QIP to MetaIP for DHCP services and so far we have had two issues when MetaIP has been implemented for VLAN that has an unauthorized Linksys router giving out IP addresses.
If you have an IDS such as Snort configured on your network, it would be fairly straightforward to build a configuration watching for DHCP traffic on specific VLANs not originating from legitimate servers (as defined by you, The Administrator). Find a helpful article here describing such a scenario: http://security.itworld.com/4363/ITW3542/page_1.html HTH, Matt
