You mean VPIs at the UNI are scarce? There are 256 VPs at a UNI and 4096 VPs in a switch. So there could be 256 mutlicast groups (switched VPs) at a UNI and 4096 in a switch. Of course, this does not work when private networks have to cross other networks via tunneling or via a UNI. +-------------------------------------------------------------------------+ |Rajeev Gupta Trillium Digital Systems, Inc.| |rajeev@trillium.com Los Angeles, California| | * Opinions expressed are mine alone * | +-------------------------------------------------------------------------+ |
