Hi list, I'm trying to protect the ipv6 part of our net by using the RA-Guard feature, just line we use dhcp-snooping for ipv4. Our 6500 switches recognize 'ipv6 nd raguard' without problems. But our access switches (we bought a bunch of 3560x switches with LANBase software) don't. I'm wondering if we need IPBase for that. --maarten
