Re: [c-nsp] 802.1q - Max Number of Subinterfaces
Depending on the features and speed you require, you might also take a look at 7304 NSE-100 or even NSE-150. This box can handle even more that 4k vlans.

Perhaps someone has a pointer to an official Cisco document, but I *think* almost all of the FE/GE interfaces on the 7200-series support up to 256 sub-interfaces. Thus, you'd have to have multiple interfaces to hit the chassis limit.

Re: [c-nsp] 802.1q - Max Number of Subinterfaces
Something to be aware of is the per-interface sub-interface limits for the various cards. Perhaps someone has a pointer to an official Cisco document, but I *think* almost all of the FE/GE interfaces on the 7200-series support up to 256 sub-interfaces. Thus, you'd have to have multiple interfaces to hit the chassis limit. This matters. I would like to terminate the vlans on a single g/f interface. It doesn't matter if it's a router or L2/L3 switch. 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 1 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.
