IDB limits are important. Also, for a switch, the max number of active VLANs is relevant (this is often lower than 4K). > Does the same limitation apply using SVI on a switch? L3 switches often have lower limits than a router. If you really want to terminate many thousand of VLANs in one box, you should seriously consider an aggregation platform like the Cisco 10000 or Juniper ERX. As an example, the Juniper ERX-310 (3U) can terminate 16K IP interfaces (and a corresponding number of VLANs) in one box, with hardware based forwarding.
